Bounty: 1.5 Million DOGE for the first person to create an electrum equivalent for dogecoin.

Houston, we have a problem.
The current dogechain over 1.4gb in size. This is incredibly bloated.
As time goes on, the size of the blockchain will only continue to increase, making sync times longer. Long sync times are bad because they may scare off newcomers who may need to download for hours or days before using dogecoin.
For obvious reasons, this is very bad.
Bitcoin has solved this problem by creating electrum and multibit, which are wallets that stores the blockchain online, but the wallet data locally. This allows for very small wallet sizes, with all the security features of having a local wallet.
We must do the same thing.
We have therefore decided to offer millions of dogecoins for anyone that can create an electrum equivalent for dogecoin.
If any shibes wants to help increase the size of this bounty, please donate to DMxCwo7qJphRVeC6pHcoDHaizk55pg6iNt . This address will only ever be used for the pot. Please do not tip me directly, because I need to keep track of money meant for me vs. money meant for pot.
tl;dr: Wow. Downlod much difficult. Hueg fil. need fix 2 get 2 moon. Such payment 4 fix. Such gud 4 new shibe. Bark bark.
 . 
Current Pot Size: Zero. Bounty has been paid out. See this for history
Note: I only control a portion of the total size of the pot. The rest are by individuals who have promised to give directly.
Much Generous Shibes who have contributed to the Pot:
Tuxedage, [-wolong-] (1m, give directly), thatslifeon (0.5m, give directly). tohaz (0.5m, GD) Shibe_Tabsa @ Teamdoge. mljsimone @ Hashdogs, Keebler64 , McPingvin, TheDoctor , need4doge , ummjackson, Faxon, UltraHR, UnsureSherlock, cpt_merica
Please message me with your name and donation amount if you want to get on this list.

IMPORTANT ANNOUNCEMENTS -- If you are working on this project, please check here for important updates every few days

1: I see a lot of people tipping. I've already said this once, but I'll say it again. Please don't tip if your intention is to add to the pot. Send directly. I bear no responsibility if your funds are misplaced or accidentally lost.

2: I am now aware that an android wallet exists. Although I thought it was obvious from context, let me reaffirm this: I would like a wallet that works on Windows/Mac/Linux, and has an easy to use installer, rather than necessitating some kind of android emulator to port it over to a computer. It must be newbie friendly.

#3: Langer_hans has brought up a valid point -- the current phrasing of the thread is dangerous because it encourages bad, but quick submissions, as only the "first person" gets the bounty. I am proposing changing the system; users will vote on which wallet they like best. The one with the most votes will get the bounty instead. This should encourage people to actually make good quality submissions, and also to collaborate. What do you guys think?

4: 15th of February is the final deadline for wallet entree submissions. Please message me with FULL DETAILS (including name, download information, website, user guide, other info, and so on) of your wallet to submit. Users will then get 1 week to try out different wallets and form an opinion of them. A week later, I will open up a poll for voting on which wallet is the best. Whichever wallet gets the most votes will obtain the prizepool. About 400k of the pot will be reserved for consolidation prizes, to be distributed at discretion. (So that shibes who didn't win won't feel sad).

*#5: Due to exogenous circumstances, competition will start on the 19th Feb as opposed to 15th. Sorry for the delay. *
** #6: VOTING IS OPEN. http://www.reddit.com/dogecoin/comments/1yhf5c/the_dogecoin_lite_wallets_are_complete_vote_now/ **
If you need to contact me urgently, please go to the dogecoin IRC -- #dogecoin @ irc.freenode.net and message me.
 . 
List of Submissions
If you do not see your name or entree on here within 48 hours of messaging me, please message me again until I add it.
Final Update:
Given the incredibly close results of the poll, the Developers and I have privately discussed how best to distribute the bounty. They have mutually agreed to a 50-50 split. The bounty has been paid out. Cheers.
People who have pledged to directly donate to the developers, please message me. Thank you

PSA: Clearing up some misconceptions about full nodes

It's time to clear up some misconceptions floating around about full nodes.
Myth: There are only about 5500 full nodes worldwide
This number comes from this site and it measured by trying to probe every nodes on their open ports.
Problem is, not all nodes actually have open ports that can be probed. Either because they are behind firewalls or because their users have configured them to not listen for connections.
Nobody knows how many full nodes there are, since many people don't know how to forward ports behind a firewall, and bandwidth can be costly, its quite likely that the number of nodes with closed ports is at least another several thousand.
Nodes with open ports are able to upload blocks to new full nodes. In all other ways they are the same as nodes with closed ports. But because open-port-nodes can be measured and closed-port-nodes cannot, some members of the bitcoin community have been mistaken into believing that open-port-nodes are that matters.
Myth: This number of nodes matters and/or is too low.
Nodes with open ports are useful to the bitcoin network because they help bootstrap new nodes by uploading historical blocks, they are a measure of bandwidth capacity. Right now there is no shortage of bandwidth capacity, and if there was it could be easily added by renting cloud servers.
The problem is not bandwidth or connections, but trust, security and privacy. Let me explain.
Full nodes are able to check that all of bitcoin's rules are being followed. Rules like following the inflation schedule, no double spending, no spending of coins that don't belong to the holder of the private key and all the other rules required to make bitcoin work (e.g. difficulty)
Full nodes are what make bitcoin trustless. No longer do you have to trust a financial institution like a bank or paypal, you can simply run software on your own computer. To put simply, the only node that matters is the one you use
Myth: There is no incentive to run nodes, the network relies on altruism
It is very much in the individual bitcoin's users rational self interest to run a full node and use it as their wallet.
Using a full node as your wallet is the only way to know for sure that none of bitcoin's rules have been broken. Rules like no coins were spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system work are followed (e.g. difficulty.) All other kinds of wallet involve trusting a third party server.
All these checks done by full nodes also increase the security. There are many attacks possible against lightweight wallets that do not affect full node wallets.
This is not just mindless paranoia, there have been real world examples where full node users were unaffected by turmoil in the rest of the bitcoin ecosystem. The 4th July 2015 accidental chain fork effected many kinds of wallets. Here is the wiki page on this event https://en.bitcoin.it/wiki/July_2015_chain_forks#Wallet_Advice
Notice how updated node software was completely unaffected by the fork. All other wallets required either extra confirmations or checking that the third-party institution was running the correct version.
Full nodes wallets are also currently the most private way to use Bitcoin, with nobody else learning which bitcoin addresses belong to you. All other lightweight wallets leak information about which addresses are yours because they must query third-party servers. The Electrum servers will know which addresses belong to you and can link them together. Despite bloom filtering, lightweight wallets based on BitcoinJ do not provide much privacy against nodes who connected directly to the wallet or wiretappers.
For many use cases, such privacy may not be required. But an important reason to run a full node and use it as a wallet is to get the full privacy benefits.
Myth: I can just set up a node on a cloud server instance and leave it
To get the benefits of running a full node, you must use it as your wallet, preferably on hardware you control.
Most people who do this do not use a full node as their wallet. Unfortunately because Bitcoin has a similar name to Bittorrent, some people believe that upload capacity is the most important thing for a healthy network. As I've explained above: bandwidth and connections are not a problem today, trust, security and privacy are.
Myth: Running a full node is not recommended, most people should use a lightweight client
This was common advice in 2012, but since then the full node software has vastly improved in terms of user experience.
If you cannot spare the disk space to store the blockchain, you can enable pruning. In Bitcoin Core 0.12, pruning being enabled will leave the wallet enabled. Altogether this should require less than 900MB of hard disk space.
If you cannot spare the bandwidth to upload blocks to other nodes, there are number of options to reduce or eliminate the bandwidth requirement. These include limiting connections, bandwidth targetting and disabling listening. Bitcoin Core 0.12 has the new option -blocksonly, where the node will not download unconfirmed transaction and only download new blocks. This more than halves the bandwidth usage at the expense of not seeing unconfirmed transactions.
Synchronizing the blockchain for a new node has improved since 2012 too. Features like headers-first and libsecp256k1 have greatly improved the initial synchronization time.
It can be further improved by setting -dbcache=3000 which keeps more of the UTXO set in memory. It reduces the amount of time reading from disk and therefore speeds up synchronization. Tests showed that the entire blockchain can now be synchronized in less than 3 and a half hours (Note that you'll need Bitcoin Core 0.12 or later to get all these efficiency improvements) Another example with 2h 25m
How to run a full node as your wallet.
I think every moderate user of bitcoin would benefit by running a full node and using it as their wallet. There are several ways to do this.
So what are you waiting for? The benefits are many, the downsides are not that bad. The more people do this, the more robust and healthy the bitcoin ecosystem is.

Getting Started

Hello! Welcome to our awesome /Dogecoin community!
Here you can find very useful information about Dogecoin, Cryptocurrency and more!
Let's start from the beginning.
What is cryptocurrency?
Probably you know Bitcoin, Litecoin, and Dogecoin they are cryptocurrencies. Cryptocurrency is a blockchain-based digital asset that uses cryptography to secure its transactions.
How to start?
Here is a list of things:
Wallet
Why? You need to store your dogecoins somewhere.
Types of wallets:
Paper wallet
*Instruction: *
Step 0. Follow the security checklist recommend
The first! The first step is to download this website from Github and open the index.html file directly from your computer. It's just too easy to sneak some evil code in the 6000+ lines of javascript to leak your private key, and you don't want to see your fund stolen. Code version makes make it much easier to cross-check what actuallrunruns. For extra security, unplug your Internet access while generating your wallet.
Step 1. Generate new address
Choose your currency and click on the "Generate new address" button.
Step 2. Print the Paper Wallet
Click the Paper Wallet tab and print the high-quality quality setting. Never save the page as a PDF file to print it later since a file is more likely to be hacked than a piece of paper.
Step 3. Fold the Paper Wallet
Fold your new Paper wallet following the lines. You can insert one side inside the other to lock the wallet.
Step 4. Share your public address
Use your public address to receive money from other crypto-currency users. You can share your public address as much as you want.
Step 5. Keep your private key secret
The private key is literally the keys to your coins, if someone was to obtain it, they could withdraw the funds currently in the wallet, and any funds that might be deposited in that wallet.

Mining
What do you need?
Ideally – cheap electricity and a bunch of graphics cards.
However, you can start mining Dogecoins even using a single PC. You can also mine without using a graphics card, although the progress will be slower. Mining for coins shouldn’t affect the performance of your computer on the default settings since it will only use computing or graphics power when the system is idle.
Mining for coins on a laptop is usually not worth it since it’s not powered on 24/7, the CPU/GPU power is lower, and there is a greater chance of stressing out the chips on the laptop since they’re usually packed into a tighter space, and consequently at more risk of overheating. But if you just want to mine a little bit to get a few coins to play around with, it can do the job.
How to start? Download CUDA miner and fill info inside the window.

Am I understanding the Bitcoin system correctly? Any corrections/clarification/advice would be appreciated.

So weeks (or months?) ago I started researching Bitcoin because I want to get a VPN subscription that takes payment in BTC, and because I just have a general interest in it and may buy 1 or 2 BTC as a long-term investment. It has been a confusing and somewhat daunting thing to grasp so far, and I've been reluctant to jump in until I feel fairly confident that I understand what I want to do and why. It seems that some websites/videos either focus on oversimplifying BTC to the point that they basically aren't saying anything, or they focus on the complex (to me) math and programming that drives BTC. I looked through the newest 500 or so posts in this subreddit which yielded some insight as well, but I want to just lay out my current understanding of BTC and if anyone has any corrections or advice I'd be happy to hear it. This isn't meant to be a guide. It is just me organizing my thoughts so I can better understand how BTC really works. So I'm sure I'll get some things wrong, and when I do please let me know.
THE BITCOIN PROTOCOL/SYSTEM
I understand Bitcoin as a protocol or single system that all users must interact with to buy and sell bitcoin. It is basically a giant ledger that tracks and records all BTC transactions that have ever happened on the blockchain. It started with a Genesis block which created the initial supply of BTC. After that all new BTC have to be mined in a resource-intensive process that solves a very large/difficult equation to a certain standard, in a manner that is designed to find a new solution every 10 minutes or so on average. Aside from mining BTC and receiving the reward for solving a block the only way to obtain BTC now is to receive it in a transaction, either by buying it from a seller or by receiving it as a payment/gift. I'm not too concerned ATM with how mining works in detail, as I care more about how transactions work, or how I can use BTC.
A bitcoin essentially doesn't exist as a physical object or as an ID number, rather the Bitcoin system merely tracks "who" holds BTC, or more accurately "where" BTC resides. This is accomplished via a private/public key system that uses cryptography and authentication to securely transmit and verify transactions. This is one spot where I had trouble understanding the difference between public keys, addresses, private keys, recovery seeds, wallets, etc... I think I have a better understanding of it now so hopefully the next part makes sense.
KEYS, ADDRESSES, SEEDS, WALLETS, WTF, FML
To join the Bitcoin "network" you must first have a wallet. There are a number of different types of wallet programs, services, or devices, but in the end they all accomplish the same goal, providing and managing public and private keys. A wallet is not one address, it is not one private key/public key pair, it is not a file or folder that holds any of that information.
A wallet as I understand it is what I have heard some call a "master private key", or a very long string of letters and numbers that is randomly generated by the protocol that drives Bitcoin. This "Master" is then hashed or something to give you a smaller, more manageable number that is your recovery seed. The recovery seed can be further hashed? to give you a list of 12, 16, or 24 words, which is your mnemonic recovery seed. This unique Master (or at least very, very likely unique number due to the magnitudes of randomness) is used to generate public/private key pairs when needed, and often(or always?) does so in a deterministic manner. This means that the Master would always give the same key pairs in a specific random order. So if you lose a computer or forget a password at any time, if you wrote down your recovery seed or mnemonic recovery seed you can "recover" your wallet or Master.
?1? What I don't understand ATM is how the seed knows whether you already used a key pair. Meaning if I used the first 3 key pairs of my original Mastewallet and my computer was destroyed or I lost access to my wallet software account, then say a month later I found my recovery seed written down(or someone else did) and I used the seed to set up a new account in a different wallet software and/or on a new computer, would the first 3 key pairs I request from the resurrected Master (we'll call it Jesus) MATCH the first 3 key pairs I used months ago? Or does Jesus know that those first 3 pairs were already used and immediately know to give me the 4th key pair when I use Jesus for the first time? Does the seed check the blockchain to see if its first 3 pairs have been used already before it spits out the next available pair? I assume in wallet software/hardware wallets that the wallet.dat? file is what remembers your preferences and previous address/key usage, but the seed has to somehow work on its own, independent of a saved file correct? What prevents a wallet set up from the recovery seed from reusing addresses/keys? ?1?
Once you get your Master and write down your recovery seed, you are basically ready to receive BTC. You can buy BTC from an exchange which will require lots of ID verification and linking to your bank account. This is the cheapest way to buy BTC but is also the least private and most time-consuming(setting up and providing documentation). Also an exchange keeps your purchased BTC within its own wallets until you request that they send them to another address (one you control). You could buy from an individual and pay cash, which is quicker and normally requires little to no identification, but it is normally the most expensive. The individual sends BTC to an address you control after you pay.
When you buy BTC in order to receive it a transaction has to take place. You use your wallet to create your key pair, which gives you your public key/address. You give the sender your address, which is basically a hash of your public key in your selected key pair. The sender then initiates the transfer in Bitcoin software by "signing" the transaction with his private key and publishing his public key so everyone in the system knows which addresses are involved in the transaction. The BTC software checks that the sender's private key corresponds to his provided public key/address, and notes that your public key/address is the destination.
If you want to send your BTC to another address the process is the same. You get the recipient's address/public key, initiate the transaction and sign it with your private key (the private key that corresponds to the public key/address you used to receive the BTC originally), and the BTC software checks everything. You don't actually have to know or type your private key, as the BTC software does it for you. The only typing or input you provide is the recipient's receiving address/public key and your own "sending" address/public key. And sometimes if you have an online wallet or certain wallet software it will automatically select your public key(s)/address(es) that contain enough BTC to cover the transaction.
Once a transaction has been submitted to the BTC system, it has to be confirmed by miners to be finalized and added to the blockchain. This can take minutes or hours depending on what transaction fee you pay (higher fee means higher priority and more likely to confirm fast). Once your transaction is in a block on the blockchain it is best to wait until it has 5 or 6 new blocks ahead of it on the chain to make sure it is really final, which normally takes an hour or so.
If you need to receive more BTC in the future you can use the same address as before but you SHOULDN'T since your private key was used already. You should request a new key pair from your wallet/Master and provide that new address/public key to receive new BTC. So over time you will have a history of used key pairs that you don't want to reuse, but this won't be a problem since one Master can provide an almost unlimited number of key pairs.
ANONYMITY/PRIVACY
The biggest advantage or benefit of Bitcoin is the fact that is exists and operates outside of the control of any bank, company, nation, or government. It is only a program or protocol, so to take part in it you don't need anyone's permission, you just need the technical capability to interact with the system and create a wallet. The caveat of course is that you need software that works with BTC, and if you are joining the system for the first time you need someone to send you some BTC. The Bitcoin system itself is merely a chain of transactions, identified by the address/public key. So Bitcoin itself doesn't identify any person or company on the blockchain. In this way it is KIND OF anonymous, however every transaction must be forever public and visible on the blockchain, so you could follow any recent transaction back to any number of previous transactions. So if someone was able to identify YOU as the owner of a particular address, they could say that YOU sent BTC to a specific address at a specific time in a specific amount.
I'm still a little fuzzy on this stuff but I have some things basically down I think. With online or hot wallets and probably most others you would generally install a program to your PC or phone, and/or create an account through a website. I imagine that most require an email in the least in order to sign up, although there may be some that require no personal info, and some I'm sure require more info. There is also the issue of your IP address being visible or connectable to a particular wallet website/service, and if your PC is insecure then outside entities could intercept your info.
If you buy from an exchange you will normally have to fully identify yourself, often in excessive amounts, and link your bank account in order to pay. Obviously this means that exchange service will know that you bought this amount of BTC on this date. I don't think they HAVE to tell anyone else that you bought from them, but in the case of a government investigating a person or a BTC transaction they often will probably comply I'm guessing.
If you buy from an individual they normally won't need any info from you, especially if you are paying in person with cash or via cash deposit into their bank account. This seems to be the most anonymous method to buy BTC to me.
?2? From what I've read there are many wallet services that cycle or mix BTC within their system, I think it is called shared addresses or something? Basically once you receive BTC to your address within their wallet service, they will hold it. But if it sits there long enough they may transfer it internally among their own addresses in order to keep the majority of their users' BTC safely stored on a few addresses in cold storage. They would digitally credit you with that amount of BTC, then when you want to send some of 'your' BTC they would move the amount that you want to send back to an address under your specific wallet, then you would use that address to make the transaction. So the BTC you received initially probably won't be the BTC you actually send later on. Or more accurately the receiving address you initially got the BTC on won't be the sending address you use to send that BTC later? I know that there are also mixing services that cycle addresses to obscure the trail of transactions for a fee. ?2?
Regarding your IP address, I believe many wallet services support using Tor to access their website, which should help with anonymity.
So if you had to buy from an exchange, you could potentially send the BTC to a personal wallet that has shared addresses, wait a while to let it cycle, then send to another personal wallet in another program/service, and potentially your the trail from you buying from the exchange to eventually holding the BTC in your personal wallet would be obscured?
MY PERSONAL PLAN
I haven't created a wallet or bought BTC yet personally, but want to soon. See if this scenario makes any sense.
  1. Create a mobile wallet in say MyCelium, in order to receive my first BTC.
  2. Buy some BTC via an individual willing to do cash deposit into their bank account. (If I do this will the bank ask for ID from me, or as long as I just fill out the deposit slip with the person's acct number and hand it to them with the cash will they just take it?)
  3. Once they confirm I paid and send BTC to me I confirm that the transaction is on the blockchain an hour or two later.
  4. If MyCelium doesn't do the shared addresses thing where they essentially act as a mixer, I could either send by BTC to a mixing service or to another wallet that I create in say Electrum or Multibit HD(assuming one of those do the shared mixing thing).
  5. Then once I feel confident that everything has been mixed I can send my BTC to another wallet, maybe Electrum/Multibit HD (whichever one I didn't use already) to act as my final BTC wallet.
  6. After that I could send all or part of my BTC to a hardware wallet like KeepKey in order to safely hold my BTC for extended periods.
?3? At what points in the above scenario should I use Tor to obscure my IP address, assuming each of those wallets support it?
Also, am I going completely overboard if I will be buying from an individual via cash deposit? I figure this process would be better applied if I bought via an exchange, but if I buy local is this all pointless? All I'm planning to buy is a VPN service, and possibly buy more BTC to hold as an investment. It's not like I'm buying drugs or doing other dark web stuff. I'm mostly just interested in increasing my privacy in relation to my ISP and advertisements, especially in light of the new ISP/internet laws that have been passed/repealed. (I'm in the USA). ?3?
TLDR:
My main questions revolve around how wallet addresses/seeds work in practice, and how I can maximize my privacy/anonymity when using BTC.
Thanks for any comments

How to Trade Bitcoin Part 1: Getting Ready to Trade

The first part of our bitcoin trading guide series explains the basics of bitcoin and trading terminology. Instructions are also provided for buying bitcoin and getting ready to trade on BTC.sx. We originally produced the first part of this guide for our own traders to get started with our platform. However, after some really good feedback we thought we should share it publicly too. So please bear with us if it is quite orientated to our own platform. Future parts will be much more applicable to trading in general.
Here is what we have planned for the series:
1) Getting ready to trade (this post)
2) Making your first trade
3) Basics of technical analysis
4) Advanced TA
5) Developing a sustainable strategy
Please let us know if there are any topics you would like specifically covered and whether or not articles are the best format for learning.
Why should you listen to what we have to say?
Our CEO turned $100 into $200k by trading bitcoin, our COO previosuly worked at senior management level at Deutsche Bank and UBS, and one of our advisers has a Wall Street background as a Portfolio Manager and is a Chartered Market Technician.
http://i.imgur.com/G06P306.png
This article begins with an overview of bitcoin, how to buy bitcoin and how to manage risk. The remainder of the article focuses on understanding trading terminology and creating a bitcoin trading account on BTC.sx.
What is bitcoin?
Bitcoin is a digital currency that uses encryption, rules of mathematics and a decentralized network to control the creation of more bitcoins and verify transactions. Bitcoin was designed to operate as ‘digital gold’ — it resembles a commodity but can be used as a currency. Bitcoin can be traded for fiat currency, like dollars or pounds, creating opportunities to profit from trading price fluctuations.
http://i.imgur.com/hNnKxGE.png
Why is bitcoin so volatile?
Compared to the price of gold, the price of bitcoin has exhibited much larger price swings. Typically the price of gold will change by just a few percent each week, but bitcoin’s price often changes by 10% or more — even in a ‘flat’ market.
Volatility is generally considered a good thing by bitcoin traders because it creates opportunities to buy lower and sell higher than flat markets.
The primary reason why bitcoin is volatile is because it has a small market cap and low trading volume. Market cap is the number of units (bitcoin here) in circulation multiplied by the value (bitcoin price here).
For example, bitcoin has a market cap of about $3 billion vs $31 billion for the a gold ETF (GLD is the most popular American gold investment vehicle). Additionally, the daily average trading volume for bitcoin is about $12 million vs approximately $939 million for the gold ETF.
The result of this small market cap and low trading volume is that less trading less money is required to make a large difference in supply and demand.
For instance, if a trader wants to buy $3 million worth of bitcoin this represents 33% of the daily trading volume and would push the price up approximately 14%, at the time of writing. However, buying $3 million worth of the gold ETF is just 0.3% of the daily trading volume and is nothing compared to the hundreds of millions of trades that influence gold’s price.

2. How to Manage Risk
Risk of buying bitcoin
As discussed above, bitcoin is an extremely volatile asset. Besides increasing in value, bitcoin’s price can also dramatically fall. When buying bitcoin, never invest more than you can afford to lose.
You cannot lose more than you put in, so don’t put in more than you can afford to lose and you’ll be all right, even in the most negative case. - Rpietila, Bitcoin and commodity investor
Risk of trading bitcoin
Furthermore, investing more than one can afford to lose reduces a trader’s ability to make good decisions. In particular, there is a risk of ‘panic selling’ when the market declines slightly. Instead of holding throughout a market dip, someone who is over-invested may panic and sell-off their holdings for a low price — attempting to cut their losses. This tends to lead to losing more money when the market recovers and the trader buys back at a higher price.
http://i.imgur.com/yrQbCsI.png
Simply, the best way to manage your risk is to not invest more than you can afford to lose. At BTC.sx, losses cannot exceed your deposit — so simply make sure this is a comfortable amount for you to trade with.
3. Understand Basic Bitcoin Trading Terminology
Trading
Trading is the act of buying, selling or exchanging one asset for another. Exchanging Bitcoin for US dollars, for instance, is trading.
Position
A position is similar a trade, which can either be long (buying bitcoin) or short (selling bitcoin). Like a trade you profit from a long/buy position when the price rises; and you profit from a short/sell position when the price falls.
Unlike a trade, a position has an open and close. At BTC.sx you begin by depositing bitcoin. Then you may acquire more bitcoin or US dollars by opening a position. When the position is closed you are left with just more or less bitcoin than the value deposited — this depends on how profitable your position was.
Trading platform
A trading platform, like BTC.sx, is a place where traders go to enter positions. Unlike an exchange, it is uncommon for to use platforms for exchanging one asset for another. Typically trading platforms also include more advanced features, such as leverage.
Leverage
http://i.imgur.com/Aik56aI.jpg
Leverage is borrowing assets for the purposes of increasing potential trading returns. This is also known as margin trading.
Trading with 10x leverage on BTC.sx, allows you to deposit 1 bitcoin and trade with 10 bitcoins. When you are done trading (closing a position) you return the 10 bitcoin and keep any profits made.
For example, let’s say your trading has been going well and you are consistently making a 10% return each week. Trading with 1 bitcoin, your profit is 0.1 bitcoin. However, with 10 bitcoins your profit is 1 bitcoin — this is the power of leverage when used correctly.
Although leverage does also increase trading risk exposure, your losses can never exceed your deposit at BTC.sx. Furthermore, your risk of an exchange failure is reduced because you are trading with 9 bitcoins that belong to BTC.sx and only 1 bitcoin of your own.
Exchange
Unlike trading platforms, investors use exchanges to swap an asset for another. For example, Bitstamp allows investors to trade their local currency for Bitcoin, or vice versa. Exchanges are the main determinants of bitcoin’s price because they contain an order book.
At an exchange you can either be a market maker or a market taker.
Market maker
A market maker sets the price they wish to buy or sell at and waits for a market taker who agrees to that price.
Market taker
A market taker finds a market maker that is offering a desirable price and quantity then immediately trades with them.
Order book
An order book is a list investors wanting to buy and sell an asset at specified quantities and prices. These are the market makers. Below is an annotated explanation of a bitcoin exchange order book. Picture the order book as a very hectic auction and the concept should be easier to understand.
http://i.imgur.com/DuRYrnx.png
Sell orders: “Asks”
This part of the order book lists the prices and quantities investors wish to sell bitcoin at. Here the cheapest seller is offering 2.3467 bitcoin at a price of $244.58. As these investors are asking for a price to sell at, these are called asks.
Buy orders: “Bids”
This part of the order book lists the prices and quantities investors wish to buy bitcoin at. Here the most expensive buyer is willing to purchase 0.5 bitcoin at a price of $244.43. As these investors are bidding for a price to buy at, these are called bids.
Current bitcoin price
This is the last price at which bitcoin was exchanged for US dollars. Given that buyers will fulfill the cheapest ask, and sellers will fulfill the most expensive bid, the price will always fall between the the cheapest ask and most expensive bid.
In this example, the price is $244.39 — the same as the most expensive bid. This means that the last bitcoin trade was a market taker selling to a market maker. This is also a demonstration of a seller always wanting to sell to the highest bidder.
Order book depth
This depth graph visualizes the amount of asks and bids at various prices. The more bitcoins that are available at a price, the ‘deeper’ the graph is. Naturally, as sellers do not want to ask for cheap prices and buyers do not want to buy for expensive prices, the graph is normally shallow in the middle.
If the chart is one-sided, it suggests that the market may be feeling bullish or bearish. In the above example, a lot of investors want to sell at $245 which would make it difficult for the price to rise beyond that. Conversely, the shallow graph on the bid side shows not many people want to buy bitcoin at these prices. This is typical of a bearish market.
Order book execution
An important feature of BTC.sx is that the positions our users open/close make buys and sells on exchange order books. In practice, when our users click buy, US dollars is used to buy bitcoin from the order book bids. Conversely, when our users click sell, bitcoin is sold for US dollars from the order book asks.

Why is this important?
Firstly, when you trade on BTC.sx you do so with leverage. This means you can have a larger impact in the market and move the price in your favour. In the above example using just 1.3 bitcoin at 10x leverage would create buy 13 bitcoin from the asks. This helps drives the price up because now the cheapest ask is $244.61. If the market sees this as a bullish sign then others may follow, sparking a price rally.
Secondly, order book execution means that BTC.sx does not trade against our users. Trading platforms that do not offer this execution are acting as market makers and stand to profit from their traders losing money. At BTC.sx we want our traders to be profitable so they can keep trading.
*4. How to Buy Bitcoin * As a bitcoin-only trading platform, BTC.sx only accepts bitcoin deposits. This allows you to begin trading in minutes and without verifying your identity.

I just saw this one and had a doubt, does wallet leaks my IP? Does vpn requires special config for wallet?

Avoid Thin Clients and Hosted Wallets
Almost all thin clients leak which addresses you own to whatever Simple Payment Verification (SPV) server they connect to. Thin clients do not store the blockchain locally. Instead, they query a single SPV server for the transactions that involve the addresses in your wallet. While this functionality is far more efficient and fast than parsing the blockchain locally, the trade-off is that every Bitcoin address you own is submitted to the SPV server.
Some thin clients, such as Multibit, have the capability of using bloom filters to help conceal which addresses you own by requesting extra transactions that don’t involve your wallet. However, Multibit currently favors efficiency over privacy and does not utilize bloom filters for address anonymization. The Electrum thin client doesn’t use bloom filters at all, so just like Multibit, any server you connect to knows every address that you own.
Hosted clients are even worse in terms of anonymity. All of your private and public keys reside on 3rd party servers, so it is trivial for the operator to know which Bitcoin addresses you own. Additionally, any other information you’ve submitted to the service is associated with your Bitcoin addresses and can be easily accessed by the service’s operators.
These types of wallets make it easy for a SPV server operator or service administrator to not only know which Bitcoin addresses you own, but also associate them with your IP address. The operator could potentially publish the information, they could be hacked and the info stolen, or they could be subpoenaed or NSL’d to provide logs to law enforcement or government agencies.
One of the fundamentals of Bitcoin is not having to trust any single party. In terms of anonymity, it’s best to use a full Bitcoin client like Bitcoin-Qt or Armory, and store the entire blockchain locally.
tl;dr; Thin clients and hosted wallets leak which addresses you own — use a full client like Bitcoin-Qt or Armory instead.

You will not be able to sell your Bitcoins

I hope to keep this short and succinct. If you own Bitcoins right now, I want to make it clear to you, that the vast majority of you won't be able to sell your Bitcoins when you plan on doing so. As a consequence, you will be left holding the bag when the scheme implodes. You can pat yourself on the back if you escape this madman's scheme with half your present paper value.
Here are a few reasons:
  1. You have a wallet that doesn't work. Multibit used to be the most popular wallet, but it no longer functions. The Bitcoin core wallet needs to synchronize with the rest of the network before you can send your coins, this will take hours if you're lucky, days if you're not. Don't place your faith in things designed by computer programmers.
  2. You're going to screw it up. You'll send your bitcoins to a wrong address, you'll send them with too little fee, or you'll send them to an exchange that stopped accepting deposits, or you do something else that leaves you without your coins, or with the coins hanging in limbo. This already happens continually. Good luck figuring out what went wrong when you're busy panicking.
  3. Your usual place to sell your coins will stop functioning. Most exchanges tend to shut down or fail to function during moments of chaos. If you directly sell your bitcoin to another party, the party may run out of money to pay you for your coins.
  4. It takes time for you to sell your Bitcoins. You spend 33% of your time asleep. You also can't sell while you're showering or driving. I remember when Bitcoin crashed 50% in four hours. That can easily happen again. Keep this in mind: Even if you find a place to sell, sending your bitcoins to the exchange will probably take hours. When you want to sell, the blockchain will be filled to the brim with transactions. I sold early, because I anticipated that it could collapse spectacularly, leaving me with no way to get out. I won't risk such a thing.
  5. Bitcoin wouldn't have value without the institutions that support its use. The Bitcoin protocol is likely to fail. What do I mean with failure? It can't scale well. It currently uses 0.12% of the world's electricity, but it can't handle a fraction of the transaction a bank or a credit card company manages to handle. If it grows in use it grows in value, which means its electricity use grows too. As a consequence, governments become forced to intervene. The Chinese government could kill Bitcoin overnight, by forcing miners to mine empty blocks. This would be sufficient to end Bitcoin as a practical force to be reckoned with. Perhaps most importantly, the exchanges can't handle the growing demand for Bitcoin. If everyone tried to sell, a big choke point would be the withdrawal of dollars from an exchange. If the exchanges fail badly enough, like Mt Gox did, you won't even be able to tell the price of Bitcoin. Similarly, the wallet services can fail. If Google can't handle the death of Michael Jackson, how would blockchain.info handle the collapse of Bitcoin? Perhaps worse, entire full nodes have been disconnected from the internet through DDOS attacks, simply because they ran an unpopular version of the Bitcoin protocol. When the blocksize war erupts again, you may find your own Bitcoin wallet will be unable to connect to full nodes. The more potential points of failure a system has, the greater the chance that the system as a whole eventually fails to deliver its product. Bitcoin has a ridiculous number of failure points.
As someone who bothers to read before investing in something, I can inform you that Bitcoin is a nice technology but fundamentally flawed and growing much too fast. Most of the intelligent people who entered the cryptocurrency world years ago have moved on beyond Bitcoin by now. There are many different problems with Bitcoin: A hardcoded 1MB blocksize limit, a dependence on wasting energy, a 2 week period before the difficulty algorithm is reevaluated, a mining algorithm that favors centralization in the hands of a Chinese cartel, and a public blockchain that's easily subjected to blockchain analysis.
The consequence people don't understand is that Bitcoin is a profoundly risky investment. There exists an illusion of control, of decentralization. You think you know what you're doing, you think you know how to get out, you think you know how the system behaves. If we assume that Bitcoin is a bubble, it follows from this that the gains of the early adapters, must come at a cost to those who bought in at a later stage. Those who are most vulnerable, are those who were skeptical at first but proceeded to buy in after all after witnessing the wealth gained by the initial investors. They're buying in now, hoping to find a "greater fool" in the future to sell to, but it's likely that the greatest fools will tend to be the people who look for greater fools to sell to. For more on this, I recommend reading this article and this article.
You think you own thousands of dollars worth of Bitcoin, but when the time comes to claim that theoretical value, you'll find that it won't be there. A lot of gullible people are going to find themselves hurt by this. The human mind is very much a responsive phenomenon. It doesn't anticipate disruption, it extrapolates the past onto the future. People who buy Bitcoin, buy it because they see it's rising in value and expect that this will continue. They don't buy it because they use it. When was the last time you used Bitcoin to make a purchase? An object can't derive sustainable value from the fact that people expect it's value will rise in the future.
My suggestion is to get out while you can. The phenomenon of cryptocurrency won't go away, but Bitcoin is an embryonic technology that will be replaced by superior alternatives. Until then, I'm quite happy if I can help prevent a suicide or two.

Sent money on a weekend day to an acquaintance

This is my first post on Reddit and this subforum for that matter so hopefully it follows the Comunity guideliness.
I wanted to share with you guys a real life experience with Bitcoin I had recently. It includes some of the good and bad parts of Bitcoin.
I think it's important at first to let you guys know about where I live. I live in Romania in a city with a little over 100.000 people. There are a few financial services francises here, however most of them are closed over the weekend. I am talking about services which allow you to send money instantly or have a short processing time.
Yesterday (Saturday) an acquaintance contacted me to help him out with a loan. He couldn't wait until Monday for the bank transfer to be processed as the matter was quite urgent. Western Union was my first choice, but after a brief Google search I found that all the vendors that offered their service were banks and are closed over the weekend.
The second choice was through a gas station station francise which offers instant money services. However that didn't work either because they closed shop at 4PM, and it was passed that.
I didn't know if my acquaintance had any experience with Bitcoin, but I thought to ask him anyways. As it happens he was well aware of Bitcoin and digital currencies in general. He quickly installed Multibite, created a wallet and sent me his address. By the way he lives in Bucharest (capital of Romania) so I knew ATMs are available for him to be able to exchange the BTC and withdraw the money in the same day.
The process of sending him some BTC was flawless and quite satisfying after all the hassle I went through with the local instant money services. Brace yourselfs because now comes the bad part of Bitcoin. He went to a bunch of said ATMs only to discover that some of them were not functioning anymore whilst others were just for buying BTC with fiat money.
Long story short, he wasn't able to exchange and withdraw the BTC and had to sent them back to me. The good part is that the back and forth transfer fees were very low.
Today I sent him around $100 using one of the gas station instant money services... after about 10 minutes of waiting and writting a form which pretty much required all the information off of both our identity cards. He had to do the same thing to get the money. The commision was $5.

Electrum security/privacy model?

The Electrum homepage states that Electrum is:
Low trust: Information received from the servers is verified using SPV. Servers are authenticated using SSL [my emphasis]
https://electrum.org/index.html
However, I'm having a hard time finding documentation on how Electrum servers work and more specifically how they implement Simplified Payment Verification (SPV) as defined in Satoshi's white paper.
The Bitcoin Wiki states:
ThomasV claims that "Electrum, it is doing SPV since 2012".
https://en.bitcoin.it/wiki/Thin_Client_Security#Electrum
I found a conversation between Greg Maxwell and Mike Hearn from late 2012. One of the messages included this passage:
I'm concerned about how the particular security model of electrum is being described; or rather— not being described. The electrum website appears to have no security discussion beyond platitudes like "Secure: Your private keys are not shared with the server. You do not have to trust the server with your money.", "No scripts: Electrum does not download any script at runtime. A compromised server cannot compromise your client."
http://sourceforge.net/p/bitcoin/mailman/message/30108843/
Later Mike writes that he was able to contact ThomasV with his concerns, and that progress was made in addressing them.
A late 2013 question posted to Bitcoin StackExchange raises similar questions:
http://bitcoin.stackexchange.com/questions/16629/is-electrums-spv-thin-client-implementation-not-p2p-as-opposed-to-multibits
The answers seemed confusing at best.
I'm pretty clear on how SPV is supposed to work, but so far the documentation I've found suggests that Electrum does not fit the description.
Electrum clients apparently connect to a single trusted server. It's unclear to what extent that server logs traffic, how/if Bloom filters are used to increase privacy, or even how the client proves that transactions coming from the server are in fact in the the block chain.
Can anyone point me to some technical documentation on the Electrum security/privacy model?
I've seen this source repository (not sure it's the right one):
https://github.com/spesmilo/electrum-server
It's sparsely documented, there's no test suite to speak of, and there seems to be far too little code for a full SPV implementation.
Edit: after reading responses so far and digging around some more, it appears that Electrum is doing SPV as indicated in the Wiki. There seem to be two main differences between Electrum and BitcoinJ (another SPV implementation used in MultiBit and other wallets):
  1. Electrum clients connect to a single trusted server chosen by default at random from a list posted to irc. BitcoinJ nodes connect to multiple peers and compare responses to detect withholding attacks.
  2. BitcoinJ nodes use Bloom filters and Electrum does not. This feature is intended to obfuscate the exact transactions being requested by a node so as to avoid leaking the wallet's private public keys/addresses to peers.
Under both systems, the client obtains block headers, using Merkle roots/chains to match received transactions to the containing blocks.

Bitcoin is dead for micro-transactions. This fatal flaw has cost me hundreds already ...

Hello everyone, Thanks for your time :)
I'm shocked.
Does Bitcoin have a fatal flaw?
The inability to allow micro-transactions? WTF!
Recently, I spent a few hundred dollars setting up a digital ebook store.
My intention was simple ... sell ebooks and digital information - for Bitcoin.
I want to price my products at 1 cent USD, or perhaps lower.
Right now, that's worth around 0.00001304 BTC.
Is it possible to send 1 cent worth of Bitcoin to someone?
Electrum and Multibit won't allow me to send payments this low, and the current Bitcoin fee structure make this basically impossible.
Obviously, the fees exceed the cost of the ebook ...
This is a fatal flaw right?
Bitcoin is basically dead for micro-transactions!
Sure ... I understand ... I can send a million for just 10 cents, but what if I want to pay a few cents for a well written piece of information? Is that currently impossible with Bitcoin?
If so, then I am really sad ...
I thought Bitcoin was supposed to address this issue, and offer some kind of alternative to the credit card systems. Please tell me I am wrong!
If anyone has any information on this, please let me know.
Are there changes comes, to allow micro-transactions or is the Bitcoin network doomed forever?
UPDATE
Thanks for the great replies. It seems my concerns were valid.

[SCAM][UNSOLVED] BTC-e APPROPRIATED MY COINS WORTH NOW 6000$

What happened:
Long story short: BTC-e forced everyone to change their passwords via link they send you to your e-mail due to ''security reasons'', if you did not changed it in time, your password expired. Turns out I lost access to my e-mail (2fa, phone lost), BTC-e closed my last ticket (with no answer) to change my e-mail where I sum up everything they asked me to do previously (and everything they asked me to do I DID) in order to change my e-mail, their last contact was 28th february, 11 days ago, that is 264 hours now, not 72 they give themselves to answer, they probably illegally blocked me from my funds by voiding my password through expiration without my consent and do not want to change my e-mail in order to restore my access after I fulfilled every single of their demands.
Detailed story:
BTC-e expired everyone passwords, assuming they did not changed them in time, and demands to change them via link they send to your email associated with your BTC-e accocunt. In order to change my password, I have to log to my email which I do very rarely (explanation further ahead). My e-mail is being protected by 2fa, phone is lost and as result, I can't access my email. I tried to recover my e-mail through Google, all I've got is automatic confirmation that they accepted the request and it takes them usually 3-5 days to respond. It's been about 2 weeks right now, no response and I am not sure if they will respond at all. Sent them another account recovery ticket, we will see what happens.
In meantime, I asked BTC-e for help, they responded and told me that they will have to manually change my e-mail and will need informations about my account: transaction history, methods of deposit, history of ip entries etc. After fulfilling their request, they asked for screenshots to the exchange transactions deposits from my wallet and I did that as well. Then they asked for deposit from the same address and the same wallet I use to deposit funds to BTC-e. Unable to do that at first (since Multibit HD does not allow you to choose specific address to send from just like that and at that time I had little knowledge about wallets since never before I had any problems to deal with and basic knowledge how to send/receive was enough), I proposed them that I could prove my ownership by signing address and all they would have to do is to verify it. In said proposal, I included address with message and signature.
Their response? ''send coins from the wallet xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'' where x's is the address I signed and used to deposit coins to my BTC-e account before I lost access to it, so basically their answer was ''no'', judging from how they totally ignored my proposal. After sending them another message where again I inform them that it is impossible (that is what I thought so at that time, believing I can't send deposit from specific address) to do so and once again offer to prove my ownership by signing address, they told me to contact gmail to restore my email access. After asking for help how to send coins from specific address, I managed to send coins from address they asked for, all I had to do was to empty all addresses in my wallet form coins and send them back to address I wanted to use, so only that one specific address would contain any coins. Not really hard, little bothersome, but shame I did not know that earlier, it would save me a lot of time. After that, BTC-e remain silent and do not answer me (1st ticket was closed automatically due to me not responding in time as I was gathering all the data BTC-e asked for, but that was not an issue as I provided all the data they asked for from 1st ticket in 2nd ticket that is the one being most well documented and being ignored and 3rd was closed without answer, maybe because they considered it spam, as I had in total 2 tickets where I ask to change my e-mail, but if they had time to close it, they should have time to answer the second one they did not answer for so long). They say that it could take them 72 hours to answer, well, their last answer was over 10 days ago and I've fulfilled their last request 6 days ago, informing them about it. I even opened another ticket (that was the 3rd one) asking for e-mail change and sum up everything they asked me for (and everything they asked for, I have fulfilled). That was 3 days ago and on the second(!) day they closed that ticket with no answer, conclusion is simple - they simply ignore me now.

Additional Notes:
On 02.10.16, BTC-e admin announced changes related to the use of passwords, meaning they will expire and will have to be changed. Here is full announcement:
Quote Update: Security
02.10.16 08:54 from admin Please, be aware of the latest important changes in our security policies:
  1. Security:
Due to the increased cases of account hacking we decided to implement some changes related to the use of passwords:
1.1. Starting from September 30, 2016 all BTC-e accounts will undergo the password changing procedure. - On your first login to account you will see a notification that your password has expired. You will be asked to reset your password. A message with a confirmation link will be sent to your e-mail. You must click this link in order to receive a new password. Make sure you save your new password in a secure location, otherwise you will have to recover the password again. - After the first password reset your account will not be blocked. But if you reset your password for the 2nd time and further your account will be blocked for 48 hours (the standard blocking according to BTC-e rules). 1.2. Changing the password from within your BTC-e account: - If you are already logged in to your account and you remember your current password, you can change it via the Edit section of your BTC-e profile. Go to https://btc-e.com/profile#edit/home and click Reset Password. A message with a confirmation link will be sent to your e-mail. You must click this link to get a new password. Make sure you save your new password in a secure location. 1.3. Password Expiration: You will need to reset your password every 6 months. After this procedure your account will not be blocked. 1.4. We added an automatic e-mail notification to inform you of failed login attempts to your account. 1.5. The option of using an own password is added. To change the password you need to go to the "Edit" section https://btc-e.com/profile#edit/home and press the “Own password” button. The following message will be displayed: “Further instructions were sent to your email address”. You will need to click the link in the email and enter your old and new password. The requirements for a new password are as follows: minimum length: 12 characters; at least one uppercase letter; at least one lower case letter; at least one number. Make sure to save the new password.
  1. BTC-e code:
The following terms and conditions take effect as of September 30th 2016.
2.1. When creating a BTC-e code you can specify the username of the BTC-e customer, who can redeem this code. If the username is correct, the code can only be redeemed by this specific user (or the user who created the code). If the specified username is invalid (spelling error or the username does not exist within BTC-e), the code can only be redeemed by the user who created the code. If the Username field is left blank, then the code can be redeemed by any BTC-e user who receives it (as well as by the user who created the code).
2.2. Expiration of BTC-e codes: - BTC-e codes will be active for 120 days since creation. If no one redeems a code within 120 days, the code will become inactive. An inactive code can only be redeemed by the user who created it. For BTC-e codes created after January 1, 2016 the 120 days of lifetime will be counted starting from September 30th 2016.
Best Regards, BTC-e Support
I do not know if said operation was needed and if it was right thing to do to implement it. What I care for is fact, that we are not obligated to track BTC-e news and check our e-mails every week to be updated on what is going on, as nobody expects that exchange will simply void your password just like that, and, as a result, block access to your account. Since I exclusively play long, I only log to my e-mail associated with my BTC-e account in order to take a look at transactions/do some technical stuff regarding my BTC-e account and it happens VERY rarely. Last time I logged on was months ago and when I visit BTC-e site, I only take a look at trade page to see what the current prices are. It is then pretty self explanatory that one could not know about this operation at all and as long as you could argue that it is in your own good interest to keep track of the exchange you use, I hardly see how letting people know in advance about expiring passwords justifies anything, because way BTC-e handles problems that emerged regarding passwords expiration is, to be straightforward, simple theft, ill will or malicious intend, call it whatever you want, as they offer you no way out of this regrettable situation, prolonging this whole ''e-mail change procedure'', obviously hoping that they will discourage your further efforts to regain access to your money. After you hard-press them, they start to pretend you don't exist.
Being ware that I could be the one who is wrong here, I offer my apologize to BTC-e in such case, but for now, my stance on this is clear. After ignoring me for 11 days, I warned them that I will publish this and eventually take legal action against them. They chose to continue this. We will see what comes next.
Edit 1: They started to loop their messages http://imgur.com/a/LafgW Also, they deleted my post in their official russian thread: http://imgur.com/a/XB28E I issued them negative feedback that will be deleted AFTER they resolve my request: http://imgur.com/a/iSYRd Edit 2: Again, they deleted another my post: http://imgur.com/a/DmQhg
Edit 3: BTC-e is not giving a damn and they are not going to resolve my request: http://imgur.com/a/y6vdb
Edit 4: No point in keeping in touch with them and ask to fulfill their obligation. Also, since posting my correspondance with BTC-e starts to resemble soap opera by now, this will be last update regarding our messages until they send me something significant: http://imgur.com/dIVDLH8 (also, notice how they still stubbornly argue that I want to restore access to my email, while I want to change it).
Edit 5: I have started spreading the word further:

go here to buy bitcoin also known as an exchange https://coinbase.com/?r=52dee75a8a2eed3e480000e5&utm_campaign=user-referral&src=referral-link
don't create wallet, click sign up button on top right. add bank information, and credit card info, and phone info - phone allows 2 factor authentication so your identity becomes much more difficult to fake and steal your money and information. I asked them to send me a SMS message instead of using app. this is the most reputable place to do this at. Never never use an online wallet!!!
buy some bitcoin on coinbase.com, and send yourself some bitcoin using your multibit wallet address(under the Request tab it shows your address there)
Now Dogecoin First get a wallet, - use the qt wallet. You can get it here for either Mac or Windows. http://dogecoin.com/ for linux use this guide - http://www.reddit.com/dogecoin/comments/1tvmnd/dogecoin_on_linux_the_complete_beginners_guide/
For a place to buy dogecoin. Use cryptsy, here is the link. https://www.cryptsy.com/users/register?refid=138894
click register new account. enter your information. go to your settings, and enable 2 factor authentication, use your cell phone number, and put in the number that they send to your phone. This makes it much more secure. you will send your bitcoins here and then buy dogecoin, then send the dogecoin to your wallet on your own computer. Backup the wallet after every purchase.
Send your Dogecoin to your own wallet. backup your wallet, at least 3 times. Use USB thumb drives. FYI, This might take away, the withdraw servers are slow as of right now. Took 3 days for me.
If you have any questions ask. Also you can buy Dogecoin or Bitcoin on ebay, do that at your own risk.

0.085 BTC bounty: help me get my coffee and find out where did the coins go

A few days ago, I decided to buy some coffee from http://roaststation.com/. I clicked Pay With Bitcoin, copied the payment address, pasted it into my MultiBit wallet, sent the payment, and clicked back in the browser window. Unfortunately, the way the site works is when you click outside the payment pop-up box, the box closes, so I couldn't confirm the payment and get the confirmation number that I need as reference when entering my shipping address.
I wrote JB Allen, the site manager, about this; he contacted Coinbase, the payment processor. They contacted me; everybody was very nice, but it turns out that nobody got the money I sent.
So where did the money go?
Here's the transaction: https://blockchain.info/tx-index/bfc5c8eb087c0c714575edc822d6c44f58961a1e0dd76cc84adcf308ded99537 The receiving address is 1K3hRyJU8Zv8kDEgd7Dt6pKjhsxJWpLoCG. You can see that this was its first ever transaction, and the output was spent an hour later, so it's a real address.
I it possible (though, after reviewing the information I have, it doesn't seem very probable to me) that I copied a wrong address from somewhere else.
There seemed to be some other glitches in the Coinbase payment pop-up (I can post details) which also leads me to believe this was also a glitch on their part.
Anyway.. Since it seems I've lost the coins anyway, I'm willing to give 0.085 BTC to anyone who might find doing this research fun and can help me get my coffee. This might include eg. proving that the 1K3hRyJU8Zv8kDEgd7Dt6pKjhsxJWpLoCG address belongs to Coinbase, or finding its owner and getting them to return the money.
Thanks!

Dirty lier fanobets - they kept their lies even their bots already banned 2days ago.

You — Please update your info Albert i wanna withdraw my money as skins, but why im forced to change my money as bitcoin? Albert It seems your Fanobet bot was banned by Valve. You won't be able to withdraw/deposit anymore. Your Fanobet skin account balance will be converted into 65% worth of Bitcoins. This is a normal convertion rate, you would get the same while trying to sell your skins on Opskins and similar websites, because 100$ worth in skins isn’t as valuable as 100$ worth in real money. Accounts will operate with mBTC. 1 Bitcoin = 1000 mBTC. So if you have 100$ on your account, 65% of it will convert into 0,11 Bitcoin (at current exchange rate) and you will have ~110 mBTC on your account then. How Bitcoin currency works and what it is: https://en.wikipedia.org/wiki/Bitcoin It’s like real money, because you can use it in online payments. You can also add it to your Steam wallet. First of all you will need to open a Bitcoin wallet. Here's the one for Android: https://play.google.com/store/apps/details?id=net.bither Here's the one for PC https://multibit.org/ Here's the one for web: https://www.coinbase.com/ Then, you will be able to put your Bitcoin Wallet generated address into your account tab and withdraw your balance. There are also sites where you can buy Bitcoin currency: https://www.coinbase.com/ https://www.bitstamp.net/ https://www.bitfinex.com/ https://www.huobi.com/ Here you can learn about what you can buy with bitcoins. http://www.coindesk.com/information/what-can-you-buy-with-bitcoins/ You — Please update your info i never heard i must change my currency as bitcoin, but heard i should withdraw my money as skins before 8/18 gettin passed. Albert The Valve blocked our bots 2 days ago and we are no longer able to offer skins. But keep in mind that you can use bitcoins to buy/sell skins at sites like Bitskins + Bitcoins price is stable, and items are getting now much cheaper And will continue to do so. You — Please update your info so i want my "skins", not 65% bitcoins. i dont want bitcoins. i want skins. and thats ur guys promises :/ Albert According to the previous message, there is nothing I can do about it now, sorry. If you haven't got any questions I will be closing this chat. Thank you for using Fanobet. Have a nice day!

Why the fuck i have forced to change my money as 65% bitcoin?
They promised to us that we can change our money as cs skins till 8/18 deadline, but after valve did some quick bans they dont risked their money, but our money. What the fuck fanobet? why u guys scamming peoples?

Importing Private keys into a QT based wallet, how is it done?

Before the fork I had been storing my tokens in MultiBit. I saw no need to incur a transaction fee to transfer those tokens into a QT compatible wallet format prior to the fork. So now I am here with multiple files that contain the private key(s) from those wallets.
I now need to import these keys into both my Bitcoin (Cash) and Bitcoin (Settlement) QT clients. What are the steps necessary to accomplish this?
I did find https://bitcointalk.org/index.php?topic=336404.0
Is this a safe method in which to perform the activity? I will be importing to Bitcoin ABC v0.14.6 & Bitcoin Unlimited v1.0.3.0
  1. Export private key from MultiBit without password (Done)
  2. edit file with some editor like Notepad++ (I'll probably just use Notepad, unless that is a bad idea?)
  3. copy only key - this is row without # ,and you must copy only key - no date and another symbols , (row indicates that it might be better to import to a spreadsheet?)
  4. then in BitCoin-Qt open from Help->Debug window ->Console (I am able to navigate to where the Console is not located)
  5. importprivkey [label] [rescan=true]
(Where is the information I copied from step 3? and also without the '<>')
(where label is name of owner - your name.; is this necessary? Do I need to provide a label? Can I leave it blank? And if I can leave it blank would I simply omit that the '[label]' argument?)
  1. And when press enter the your address with coins will appear in your addresses and in your balance.
Additionally, can this activity take place on a computer that is not connected to the applicable network? I am still waiting (1 year 40 weeks behind) for the Bitcoin (Settlement) wallet to download the chain (for some reason copying over of the pre-fork blocks did not take and now that the fork has occurred I do not want to try to start over or run the risk of re-installing).
Thank you for your assistance.

Did I throw away 8 BTC?

I thought I knew how sending and receiving bitcoins worked, but I'm worried I did something horribly wrong. I attempted to transfer 8 BTC from my old wallet to my new one. My old wallet was created in 2011 with an old version of the bitcoin client (0.3.24) which requires me to store the entire block chain on my local drive. The new wallet was created with MultiBit 0.5.14 which does not require local storage. The block chain is enormous, and before I had finished downloading all of it I attempted to send 8 BTC from the old wallet to the new. This was ~36 hours ago. I still have not seen the 8 BTC appear in my wallet.
I am certain the address is correct. According to my old client, the transaction has been broadcast through 26 nodes but is unconfirmed. Is there a reason that I would need to download the entire block chain before the transaction could be completed? I'm worried that I did something wrong and I'm out $7,800. Any help would be appreciated, and I'll try to provide more information if necessary. Thank you.

Real-Life Superhero needs 5 btc to continue helping homeless people in Toronto! (x-post from /BitcoinCharity)

As a quick preface to this posting, I'd like to sincerely thank Moderator Frankenmint. Thank you, good sir, and I'd love to hear more of your advice and ideas!
I am asking the Bitcoin community to help me become "The World's First Bitcoin-Powered Superhero".
My name is Captain Caregiver. I'm part of the "Real-Life Superhero" community, where members like myself perform public services such as food & water hand-out patrols, anti-drug talks, and neighborhood watches.
(As proof, I was on MTV some months back: https://www.youtube.com/watch?v=MiRDxBH9YTY)
It may seem weird for adults like myself to dress up in colorful costumes, but we do it for two reasons. First, it satisfies the superhero complex all RLSH'ers possess in their psyche. Second, dressing up as a superhero while doing service to the community draws attention to the problems we're battling, such as the aforementioned homelessness. I have been doing food hand-out patrols, where I walk around downtown Toronto looking for homeless people and street kids who need help. Unfortunately, I've developed a degenerative spine condition that is now causing me pain & great difficulty in walking. I no longer have the range in mobility I need to continue my public service and the ability to carry enough supplies to give out to those without homes. And I ache to do so again!
Here is where I plead for your help, /bitcoin. I need around 5 btc to be able to buy the electric mobility tricycle I need to do my patrols again. Specifically, I am hoping to purchase a Nolet Scooter. Nolet Electric Scooters is a Canadian company, and was also on the TV show Dragon's Den. It will allow me to patrol Toronto better than ever before to help the homeless, even with my weak legs. Also, the Nolet has the best carrying capacity I've seen in any scooter, which will be great for carrying food, water & clothes to people living on the streets.
Any bitcoin donations would help me out massively and, hopefully, will bring in enough to help me help people again.
Please note I am completely willing to work with the /bitcoin community here on reddit by posting receipts for all purchases towards the "Caremobile" and supplies to help the homeless. I will also post updates and patrol reports on a steady basis to /bitcoin for two important reasons:
First, it is of utmost importance and priority to me to establish 100% trust with /bitcoin; I want to be a good example to both this community and the Real-Life Superhero (RLSH) community.
Second, I will gladly push the Bitcoin cause by saying I am "The World's First Bitcoin-Powered Superhero" in interviews and such. Heck, it's a bit audacious, but I would certainly draw attention to the wonderful potentials of the bitcoin!
I could use a bit of advice, too: I'm using multibit for my bitcoin wallet; should I use a wallet somewhere else to make things more transparent for everyone?
In any case, the wallet address I currently use is: 14Cxa1MSCccGniBdREKH951ZjaacnLa7t9
My FB page: https://www.facebook.com/rlshcaptain.caregiver which has more information about me & my personal war against poverty and homelessness. It also has many unflattering pictures of me in spandex (sigh).
Thank you most sincerely (!!!) for reading this post, kind redditors of /bitcoin! I hope we can work together on this on-going project.
Most Humbly, Your Servant in Spandex,
Captain Caregiver
Edit 1: Can I get some upvotes, please?
Edit 2: I'm sure 99% of the /bitcoin community are genuinely nice people, so it's a shame that I'm getting down-voted and insulted in the comments section by the 1% meanies. Still, I'm disappointed in the bitcoin community here on reddit but I hope I can still work with the good people in it in the future. I know I'll probably be downvoted further for expressing my honest opinion but, /bitcoin, you have to be careful of the mean & angry people here who turn people off the bitcoin cause! In any case, all my best to everyone in /bitcoin. Thank you for taking the time to read my request.

Does anyone get email notification from Bitcoin Foundation ([email protected])? Is it legit?

I don't remember signing up there and I received the email on a dedicated address for all BTC exchanges and trading sites. This is what the email says :
As some of you might know the New York Department of Financial Services (NYDFS) announced its “BitLicense” regulatory proposal in the New York State Register. We are wonderfully excited by the prospect of getting a look at the research and analysis the NYDFS had done in support of the “BitLicense” proposal, so we requested “any risk management and cost-benefit analysis (or any other systematic assessment) that is a part of the ‘extensive research and analysis’” the NYDFS cited when it issued its proposal. A prompt NYDFS response promised this information within 20 business days.
Getting that research and analysis would allow the Bitcoin community to comment constructively, helping the NYDFS match means to ends. There’s a lot of technical knowledge that could be married up with legal and regulatory knowledge if we had material to work with. Thus the bitcoin transaction method is subject to change After 23rd of April. Please see attached link to full press release which also contains instructions how to configure your Bitcoin Core or Multibit client. Open government laws could really produce their fullest public interest benefits if the community could access this information. Digitally signed press release available here.
Sincerely, Bitcoin Foundation Mark Duggan, 4002 Cattail Pond Drive, Jacksonville, 32224 FL, United States
I didn't click the link for the digitally signed press release for safety. Also, when I clicked unsubscribe from getresponse.com, the subscription name is " greenday71710" which is definitely a red flag.
My trader friend also receive the same email so I was wondering if any of you receive the same email and whether the email is legit or just a phishing.

Clearing up some misconceptions about full nodes | Chris Belcher | Feb 10 2016

Chris Belcher on Feb 10 2016:
I've been asked to post this to this mailing list too. It's time to
clear up some misconceptions floating around about full nodes.
=== Myth: There are only about 5500 full nodes worldwide ===
This number comes from this and similar sites: https://bitnodes.21.co/
and it measured by trying to probe every nodes on their open ports.
Problem is, not all nodes actually have open ports that can be probed.
Either because they are behind firewalls or because their users have
configured them to not listen for connections.
Nobody knows how many full nodes there are, since many people don't know
how to forward ports behind a firewall, and bandwidth can be costly, its
quite likely that the number of nodes with closed ports is at least
another several thousand.
Nodes with open ports are able to upload blocks to new full nodes. In
all other ways they are the same as nodes with closed ports. But because
open-port-nodes can be measured and closed-port-nodes cannot, some
members of the bitcoin community have been mistaken into believing that
open-port-nodes are that matters.
=== Myth: This number of nodes matters and/or is too low. ===
Nodes with open ports are useful to the bitcoin network because they
help bootstrap new nodes by uploading historical blocks, they are a
measure of bandwidth capacity. Right now there is no shortage of
bandwidth capacity, and if there was it could be easily added by renting
cloud servers.
The problem is not bandwidth or connections, but trust, security and
privacy. Let me explain.
Full nodes are able to check that all of bitcoin's rules are being
followed. Rules like following the inflation schedule, no double
spending, no spending of coins that don't belong to the holder of the
private key and all the other rules required to make bitcoin work (e.g.
difficulty)
Full nodes are what make bitcoin trustless. No longer do you have to
trust a financial institution like a bank or paypal, you can simply run
software on your own computer. To put simply, the only node that matters
is the one you use.
=== Myth: There is no incentive to run nodes, the network relies on
altruism ===
It is very much in the individual bitcoin's users rational self interest
to run a full node and use it as their wallet.
Using a full node as your wallet is the only way to know for sure that
none of bitcoin's rules have been broken. Rules like no coins were spent
not belonging to the owner, that no coins were spent twice, that no
inflation happens outside of the schedule and that all the rules needed
to make the system work are followed (e.g. difficulty.) All other kinds
of wallet involve trusting a third party server.
All these checks done by full nodes also increase the security. There
are many attacks possible against lightweight wallets that do not affect
full node wallets.
This is not just mindless paranoia, there have been real world examples
where full node users were unaffected by turmoil in the rest of the
bitcoin ecosystem. The 4th July 2015 accidental chain fork effected many
kinds of wallets. Here is the wiki page on this event
https://en.bitcoin.it/wiki/July_2015_chain_forks#Wallet_Advice
Notice how updated node software was completely unaffected by the fork.
All other wallets required either extra confirmations or checking that
the third-party institution was running the correct version.
Full nodes wallets are also currently the most private way to use
Bitcoin, with nobody else learning which bitcoin addresses belong to
you. All other lightweight wallets leak information about which
addresses are yours because they must query third-party servers. The
Electrum servers will know which addresses belong to you and can link
them together. Despite bloom filtering, lightweight wallets based on
BitcoinJ do not provide much privacy against nodes who connected
directly to the wallet or wiretappers.
For many use cases, such privacy may not be required. But an important
reason to run a full node and use it as a wallet is to get the full
privacy benefits.
=== Myth: I can just set up a node on a cloud server instance and leave
it ===
To get the benefits of running a full node, you must use it as your
wallet, preferably on hardware you control.
Most people who do this do not use a full node as their wallet.
Unfortunately because Bitcoin has a similar name to Bittorrent, some
people believe that upload capacity is the most important thing for a
healthy network. As I've explained above: bandwidth and connections are
not a problem today, trust, security and privacy are.
=== Myth: Running a full node is not recommended, most people should use
a lightweight client ===
This was common advice in 2012, but since then the full node software
has vastly improved in terms of user experience.
If you cannot spare the disk space to store the blockchain, you can
enable pruning as in:
https://bitcoin.org/en/release/v0.11.0#block-file-pruning. In Bitcoin
Core 0.12, pruning being enabled will leave the wallet enabled.
Altogether this should require less than 1.5GB of hard disk space.
If you cannot spare the bandwidth to upload blocks to other nodes, there
are number of options to reduce or eliminate the bandwidth requirement
found in https://bitcoin.org/en/full-node#reduce-traffic . These include
limiting connections, bandwidth targetting and disabling listening.
Bitcoin Core 0.12 has the new option -blocksonly, where the node will
not download unconfirmed transaction and only download new blocks. This
more than halves the bandwidth usage at the expense of not seeing
unconfirmed transactions.
Synchronizing the blockchain for a new node has improved since 2012 too.
Features like headers-first
(https://bitcoin.org/en/release/v0.10.0#faster-synchronization) and
libsecp256k1 have greatly improved the initial synchronization time.
It can be further improved by setting -dbcache=6000 which keeps more of
the UTXO set in memory. It reduces the amount of time reading from disk
and therefore speeds up synchronization. Tests showed that the entire
blockchain can now be synchronized in less than 3 and a half hours
(See
https://github.com/bitcoin/bitcoin/pull/6954#issuecomment-154993958)
Note that you'll need Bitcoin Core 0.12 or later to get all these
efficiency improvements.
=== How to run a full node as your wallet ===
I think every moderate user of bitcoin would benefit by running a full
node and using it as their wallet. There are several ways to do this.
(https://bitcoinarmory.com/) or JoinMarket
(https://github.com/AdamISZ/JMBinary/#jmbinary)
Multibit connecting only to your node running at home, Electrum
connecting only to your own Electrum server)
So what are you waiting for? The benefits are many, the downsides are
not that bad. The more people do this, the more robust and healthy the
bitcoin ecosystem is.

Sending and receiving Mastercoins for the novice

I'm hoping someone will be able to assist a novice with some basic questions regarding sending and receiving Mastercoins. My questions:
1) To send MSC I want to use JR's Mastercoin Advisor. What is the "data address"?
(i) Is the "data address" a new, unique address generated by the Advisor for each transaction according to what you input?
(ii) Does the unique address include the information on what is sent (TMSC or MSC) and the amount sent so that this does not have to be specified when sending the transaction from the Bitcoin-QT client -- i.e., that information - amount and type -- is included in the data address?
2) Once you have the data address, is that all you need from the Advisor? I.E., you set up a transaction manually on Bitcoin-QT, sending 3x 0.00006 BTC to each address - Exodus, MSC recipient and Data addresses?
3) Is a miner's fee required? If so, is it 0.0001 BTC? To which address do you add the miner's fee?
4) Are MSCs sent the same way as BTCs? Bitcoin-QT send the entire amount of your MSCs from the address holding the MSCs and then sends back the change to a different address in your wallet? So if I have 1000 MSC on the address and send 100 to the recipient, I receive 900 back at a different address in my wallet with a different private key? Or are they sent back to the same address? How will I know which address the change is received at?
5) When sending Mastercoins from the address holding the MSC, do I need to have sufficient Bitcoins at the same address? In other words, I need to co-mingle BTCs and MSCs in the same address? How does the wallet tell them apart?
6) Finally, if I received the MSCs from the Exodus Address in a Bitcoin client that does not support sending to multiple addresses (in this case Multibit) can I simply import the compressed private key to the Bitcoin-QT client to perform the transaction? Are there any concerns about having the same data in two clients?
That's a lot of questions. If anyone can answer any of them (you don't have to tackle them all :) if that too much trouble, I'd really appreciate it.
Many thanks.
