Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
  • Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
  • Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable - The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
  • Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
  • Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
  • Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
  • Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
  • Nearly instant - From a few seconds to a few minutes depending on need for confirmations. After a few confirmations transactions are irreversible.
  • Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
  • Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable - Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
  • If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended.

/r/Bitcoin FAQ - Newcomers please read

Welcome To The /Bitcoin Sticky FAQ

Maybe you're here because you've received a tip on social media, or maybe you've just been hearing a lot recently about Bitcoin and are wondering what the big deal is? The following videos are a good starting point for understanding how bitcoin works and a little bit about its long term potential:

What are Bitcoins worth and where can I buy them?

Bitcoins are valued at what market price people are willing to pay for them. Here are a couple useful sites 1 and 2 that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just google "1 bitcoin in (your local currency)".
You can buy or sell any amount of bitcoin (from as little as $1 worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank account. Some recommendations include:
US & Europe
Australia
China
All countries
Always do your own personal due diligence on the validity of an exchange and check the URL prior to sending them money or entering login credentials. Phishing sites are not uncommon. Use this checklist if you aren't sure which exchange to choose.

Where can I spend Bitcoins?

A comprehensive list can be found at TheBitcoinPage.com but some of the key ones are below:
Store Product
Microsoft Xbox games, phone apps and software
Spendabit and The Bitcoin Shop Search engines of online retailers accepting bitcoin with millions of results
Overstock Everything under the sun
Gyft Gift cards for thousands of retailers including Amazon, Target, Walmart, Starbucks, Whole Foods, CVS, etc.
Reddit Gold Premium membership which can be gifted to others
NewEgg, TigerDirect and Dell For all your electronic needs
Expedia, Cheapair and 9flats For when you need to get away
Wordpress, Namecheap, Mullvad and PIA Handy web services
Foodler and Takeaway Takeout delivered to your door!
HumbleBundle and GreenmanGaming For when you need to get your game on
Coinmap and AirBitz are helpful to find local businesses accepting bitcoins. UK residents can find a comprehensive directory of shops, pubs, websites and other places in the UK that accept bitcoins at wheretospendbitcoins.co.uk.
There are also lots of charities which accept bitcoin donations, such as Wikipedia, Red Cross and the RNLI. You can find a longer list here.

Merchant Resources

If you operate a business and want to accept bitcoin as a payment method, there are several options available:

Can I mine bitcoin?

Mining bitcoins can be a fun hobby but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The friendly folks at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network, you can run a full node by hosting the blockchain and propagating transactions. Here is a handy setup guide

Securing your bitcoins

With bitcoin you can be your own bank and personally secure your bitcoins or you can use trusted companies such as Coinbase and Circle which have secured wallets where they hold the bitcoins for you and provide insurance. Be sure to only deal with reputable companies, if you have any concerns about a company's trustworthiness just ask or check their consumer reviews and ratings.
If you prefer to have direct control over your coins without having to use a trusted third party you can use personal wallets for desktops / laptops, Android and iOS where you alone hold your private keys. Electrum, Mycelium and Breadwallet are popular, but there are many options.
Find a wallet that works best for you
For increased security use Two Factor Authentication (2FA) everywhere it is offered, including email! (2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access). Google Authenticator and Authy are two great apps for handling 2FA.
Additional security systems such as Mycelium Entropy (for printing multi-signature paper wallets) and the Trezor Hardware Wallet are great ways to easily secure your coins. Or, you can opt to secure your bitcoin using cold storage.
Note: Do not use brainwallets unless you are an expert, they are known to be vulnerable to theft unless set up correctly.

Earning bitcoins

Just like any other form of money, you can earn bitcoins by working for them. Here are a few resources for bitcoin jobs.

Tipping

Bitcoin Units

Note: This is a brief overview to the most commonly used Bitcoin units. For full information check out the Bitcoin Units wiki (work in progress).
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common ones are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (ml) or millimeter (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μl) or micrometre (μm)
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
Still have questions? The friendly folks at /BitcoinBeginners would be happy to help you out. If you decide to post a question in /Bitcoin, please use the search bar to see if it has been answered before and remember to follow the community rules outlined on the sidebar to receive a better response. The mods are busy helping manage our community so please do not message them unless you notice problems with the functionality of the subreddit.
Note: This is a community created FAQ. If you notice anything missing from the FAQ or that requires clarification you can edit it here and it will be included in the next revision pending mod approval. The original sticky can still be found here.

explicacion del video anterior: [SPOILER]Todo lo hace en la testchain de Bitcoin. Abre un canal con 0'04 testcoins y efectua el pago de 10000 milisatoshis para comprar la ya famosa imagen de los gatitos viendo la luna.
No hay transacción de vuelta, es símplemente un pago que se ha realizado a través del canal que habían abierto.
En la blockchain (en realidad, en la testchain, puesto que se está utilizando la cadena de bloques para pruebas que tiene Bitcoin) se ha realizado una transacción, que es la transacción necesaria que hay que hacer para establecer el canal.
La transacción de compra de la imagen (la de los 10000 milisatoshis) es la que se hace fuera de la cadena de bloques.
A ver, el canal se establece por un importe de 0'04 bitcoins (testcoins, en realidad). Una vez realizada la transacción de 10000 milibitcoins en la lightning network, el balance de ese canal cambia a 0'04 bitcoins - 10000 milibitcoins.
Pero lo bueno del asunto es que el canal de pagos es bidireccional y, se supone, que formará parte de una red (la lightning network) de manera que el balance se irá reajustando conforme las transacciones de la red vayan necesitando hacer uso de dicho del canal de pago que has abierto.
Cuando cualquiera de las dos partes decida cerrar el canal, entonces el balance que contenga en ese instante será el que se fijará en la cadena de bloques.
Las transacciones que emplean el canal de pago son "off blockchain", esto es, se realizan sin necesidad de ser reflejadas en la cadena de bloques. La única transacción que ha necesitado utilizar la cadena de bloques es la necesaria para crear el canal.
El canal no se ha cerrado, ha permanecido abierto.[/SPOILER] P.D 3:

submitted by sirpask to btces [link] [comments]

the draft email I've been asked to share - which I use when sending to friends who have asked me about Bitcoin. Feel free to critique / use & share

I wrote in another thread today about an originally 'anti-bitcoin' friend turning their opinion around and now wanting info on buying their first bitcoin. In the post I mentioned that I have a draft email which I send out to anyone who asks me about Bitcoin. (I must state, I never spam friends with it - it's only when they ask.)
wildcat55 has asked if they can see my draft email - so I thought I would share it. As stated in the title, please feel free to critique, or share and use it yourself. It's saved me a lot of effort in not having to re-type / re-hash an email whenever I'm asked.
Also, bear in mind this is meant to be an overview - and that I am UK based, so US services such as Coinbase for buying coins are not an option. There is a premium on buying through Localbitcoins - but at least it is fast & you don't have to upload loads of docs & ID.

Anyway, here it is:

Hello!
Ok, so I'm gonna try and give you all the links you need to get started with Bitcoin. It can seem like a lot to take in at first, but it's actually relatively simple when you get going! I'll try and break into sections....
First off, some background information on bitcoins:
This site has an overview of what bitcoin is, a nice short video, and has a really good FAQ section: https://bitcoin.org/en/ It also has a good 'Getting Started' section: https://bitcoin.org/en/getting-started In the link above, it gives you some pointers on choosing the wallet you want to use. It's probably the first thing you want to get set up with - and if you want to use the same provider as me, which is also one of the most trusted, then it's a wallet with Blockchain.info
Wallet: This is the link to create a new wallet: https://blockchain.info/wallet/new It's free to use (always) and has nearly 2 million users. I highly recommend you set up 2FA (Two Factor Authentication) - this is so that when you try and send bitcoins, you get a text if you've set up SMS as the 2FA method (or you can use Google Authenticator). Basically, no hacker can authorise a transaction to send Bitcoins unless they happen to have stolen your mobile phone too (which would have to be a very determined hacker!) When you have set up your wallet, check out this page about security & how to set up 2FA: https://blockchain.info/wallet/support-pages This wallet provider also has an Android & I-phone app that you can download. When you have bitcoin in your wallet, you can click on the balance to switch the display from BTC to $USD so you can easily see what your balance is.
Buying Bitcoin: I have purchased my Bitcoin from two different places. LocalBitcoins & Bittylicious (funny website name, I know!). Both are quite easy to use and I've never had any problems. With both sites you have to be willing to do a bank transfer to the seller & then the coins are sent to you. You will need to specify a Bitcoin address to send coins to, so this is why you need a wallet set up first of all. Don't be fazed by the price for one whole Bitcoin - you can buy in fractions like 0.1 or 0.15 etc etc - you don't have to buy a whole Bitcoin in one go.
First off, https://localbitcoins.com/ - this works as a middleman between buyers and sellers & is a bit like Ebay in that people have trust ratings for number of trades completed successfully. On their home page there is a buyers guide & a video tutorial you might want to check out. When you sign up at this site they get you to create a wallet with them - this is the place your bitcoin will be transferred to. As soon as you have received them, send them to your blockchain.info wallet address (there is a feature to do this) - do not keep them on their website, because they hold your private key to that address. I'm not saying they are not trustworthy, but the sooner you have your coins in your own blockchain address, the better. At this point I will make you aware that any bitcoin transaction you make is subject to a miners fee of 0.0001 BTC (about 4 pence). So if you move bitcoin and spot it has dropped by a tiny bit, this is why. By the way, potentially you could send 100 grand and it would still only cost 4 pence! this is a big advantage bitcoin has over traditional money transfer services. Oh, also in most cases the transaction is instantaneous, but can sometimes take a maximum of 10 minutes (every 10 minutes a new block is released for miners to solve, but I won't get into that now!) :-)
Take a look at the prices on offer on that site ^ and then compare them to this UK based website (which I have used the last couple of times) called https://bittylicious.com/ This one is a little bit more straight forward in that you don't have to create a wallet with these guys, you just type in your own personal wallet address (blockchain.info address) and your coins are sent directly to that. They have a buying guide here: https://bittylicious.com/help/index.php/Bitcoin_buying_guide
Be aware that both sites will probably put a limit on what you can purchase initially - but this raises as you trade more and build up trust.
News: Ok, so now you have your wallet & some bitcoin (congratulations!). To keep track of the price movements, latest news & use a handy forum, I recommend the following sites: (I have these pinned to my home screen on my phone I use them that often!)
http://www.coindesk.com/ Gives you an oversight of the current price & news articles (check their drop-down menus for more data) http://www.reddit.com/bitcoin This sub-forum of Reddit is really good to follow as a centralised place for breaking news, opinions & personal stories. They are quite a friendly bunch & a good source of info. https://bitcoinwisdom.com/markets/bitstamp/btcusd This is a really good live tracker of the bitcoin price, which you can zoom in and out of - just set the time intervals larger or smaller (15m / 30m / 1hr / etc)
Finally, when you want to learn more about the basics of Bitcoin there is a really good series of videos on YouTube called 'Bitcoin 101 Blackboard Series' - the first one is here & you can to the others from clicking on the authors channel - https://www.youtube.com/watch?v=Bhe61JaNFLU&list=PLzctEq7iZD-7-DgJM604zsndMapn9ff6q
I think that should do it for now.... If you have any questions at all, just drop me a line & I'll try to help.

A Non-technical Bitcoin Primer (Part 2)

This is a continuation of Part 1.
PSEUDONYMITY Unlike credit card transactions, in which you give your name, Bitcoin transactions are pseudonymous (a pseudonym being an identifier other than your real name). Instead of having your name on your account, you have a public key, which is just a sequence of letters and numbers, like the one below.
3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy
That's your pseudonym.
People who are concerned with privacy view this as an advantage, since it enables you to make payments without revealing your identity.
Critics worry that this system facilitates crime, and proponents counter that cash is much better for criminals. Why?
Your account may be represented by some random sequence, instead of your name, but all Bitcoin transactions that have ever occurred are available for scrutiny on a public ledger called the blockchain. This data opens up the possibility of investigative methods to which cash is not susceptible.
Also, those who are concerned about criminals may be missing the point. It's sort of like censors in the mid-twentieth century who hadn't conceived of the World Wide Web (preventing kids from being exposed to profanity these days is a bit more difficult, to say the least).
The thing they're missing is that Bitcoin is only one of many cryptocurrencies, and others (such as zerocoin) are being developed that will provide much greater privacy.
File sharing on the internet is another example of how those seeking to overregulate Bitcoin might be missing the point. Early on, we had Napster, which was shut down due to concerns over copyright infringement. The effect of this shutdown appears to have been essentially the opposite of the intended effect. Instead of stopping illegal file sharing, it accelerated the development of file-sharing technologies that were even more difficult to stop. Since demand still existed, Kazaa came to the fore, and now we have BitTorrent.
It's "hard to put the genie back in the bottle," as Ben Lawsky, New York's Superintendent of Financial Services, has pointed out. When it comes to reducing crime, overregulation of Bitcoin could lead to an increased resistance to law-enforcement efforts, as we saw with file-sharing, while at the same time taking away from its many benefits.
THREATS TO BITCOIN'S SUCCESS When evaluating Bitcoin's chances for success or trying to understand price fluctuations, it's important to keep several key issues in mind.
ADOPTION Both merchant and consumer adoption are important, and both have been growing.
On the merchant side, we now have large reputable companies accepting Bitcoin, such as Overstock.com, Expedia, and Dish Network. See, for example, the list of companies working with Coinbase.
On the consumer side, one way to track growth is to look at the number of bitcoin wallets (wallets are to Bitcoin what accounts are to the traditional banking system). This number has also been growing steadily.
The website http://www.bitcoinpulse.com/ is one place to track such things.
Another interesting thing to watch will be the MIT Bitcoin Giveaway, in which $100 in bitcoins will be given to every MIT undergraduate in the fall 2014 semester.
ROBUSTNESS OF THE TECHNOLOGY One possible threat is that some kind of bug or design flaw will cause the system to crash. The technology has been around since 2009, and Bitcoin has been resilient so far. For example, it survived a distributed denial of service attack early this year.
There are a number of design issues to consider, such as scalability, mining centralization, and so forth, but there are a lot of people working on these issues. In fact, Bitcoin is considered by some to be supported by the largest research and development community in the world. Something like 10,000 of the smartest people in the world are working on issues such as scalability and user-friendliness.
COMPETING TECHNOLOGIES There is a chance that another technology that is superior to Bitcoin will emerge to kill it. At present, however, Bitcoin is the clear leader among cryptocurrencies, and it becomes more difficult to overtake as time passes, due to the network effect.
Already, Bitcoin is supported by a massive amount of infrastructure, in the form of mining equipment, exchanges, startup companies backed by venture capitalists like Andreessen Horowitz, software applications, and so forth.
REGULATION There is some chance that governments could slow the growth of the Bitcoin economy, for example by issuing regulations that make it difficult for exchanges to operate.
Regulations in China led to a sharp decrease in the price for a time. Many governments have reacted more favorably. In the U.S., the regulatory outlook has been improving. We've seen increased clarity from the IRS and are expecting favorable regulations to come out of New York sometime this month, which may make it easier for exchanges to get established in New York. This could lead to more liquidity and would reduce the risk of shock from one exchange going down.
Moreover, the U.S. just sold about 18 million dollars' worth of seized bitcoins in an auction, which provides additional legitimacy to the currency.
A FINAL NOTE: SOCIAL AND POLITICAL RAMIFICATIONS For better or worse, one thing large-scale technologies seem to have in common is their unpredictability. Who would have predicted that a social media platform called Twitter with a cute little bird logo would end up facilitating political revolutions throughout the Arab world?
FURTHER RESOURCES This article by Marc Andreessen gives a good overview.
A nice way to get started is also to just check out bitcoin regularly. The users here range from noobs to developers and Bitcoin entrepreneurs. So, you’ll see more technical talk and in depth discussion than you see in typical media stories, and you can ask if you don’t understand.
You can also try the Bitcoin 101 Blackboard Series, which I hear is quite good.
For a quick video on the technical aspects of Bitcoin, you can try the video Bitcoin Under the Hood or the shorter, less technical version of this video.
For another explanation of the technical underpinnings, you might try the Khan Academy videos.
If you're looking to purchase your first bitcoin, then depending on where in the world you live, you might consider getting started with Coinbase. It's reputable and very easy to use. Many people will advise you not to store your coins on a web wallet, but buying a few coins (or a fraction of a coin) on Coinbase is a good way to start as a beginner. Please be aware, though, that this is a new industry and purchasing Bitcoin in any form carries risk, so do your research. I wouldn't want to be the one recommending Coinbase just before someone manages to hack it!
I hope that helps!
