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
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.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer.

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or 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.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
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, usually from a text message or app, 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.

Can bitcoin replace the gold?

Bitcoin and gold are very different assets. The cryptocurrency can’t replace gold as a precious physical asset as it isn’t a tangible commodity, while its volatility means it is unlikely to replace gold as a safe haven.
Two are very different markets to focus on; Bitcoin is a peer-to-peer decentralized digital currency first ‘mined’ in 2009, while the precious metal gold, very much a tangible asset, has been highly valued for millennia.
DIFFERENCES BETWEEN BITCOIN AND GOLD
1. Volatility
One of the most important differences between Bitcoin and gold is the volatility of the two assets. A useful measure of volatility is the average true range (ATR), which describes how much a market moves, on average, over a specified time.
Visit BtcNewz for the bitcoin price, prediction and mining.
2. Storage Procedure
A second difference between Bitcoin and gold is the way they are stored. As a physical asset, gold is stored in vaults, safety deposit boxes in banks and personal safes for smaller amounts. Bitcoins, on the other hand, cannot be stored in the traditional sense. Instead, what is stored is a secret number called a ‘private key’, which facilitates the transfer of Bitcoin from one party to another. Buying Bitcoin can be extremely risky if you do not make use of a hardware or software wallet to secure your private key.
3. Sources of Demand
Gold, as an asset, has a 7,000-year history and its drivers of demand are easily identifiable, as can be seen in the chart below. The demand for Bitcoin on the other hand, is less clear and tends to centre around price speculation, buy-to-hold strategies and the underlying blockchain technology itself.
4. Bitcoin and Gold’s Utility as Currency
Bitcoin and gold’s utility as currency is the subject of some dispute. Economists often describe money as having three crucial functions that must all be satisfied: medium of exchange, unit of account and store of value.
Medium of Exchange
Medium of exchange is the ability for something to be used as a currency to exchange for goods and services. While not widely accepted, this description fits Bitcoin; as of November 2018 organisations that accept the cryptocurrency include travel company CheapAir, gift card company Gyft, and US-based REEDS Jewelers, with many more showing interest.
However, gold is not often used as a medium of exchange in modern economies and it is not generally considered legal tender.
Unit of Account
To satisfy the unit of account function, a potential currency must be ‘countable’ so that there is something to compare the cost of goods and services against. Unit of account is satisfied by Bitcoin due to the fact that the cryptocurrency is divisible. Most transactions will be fractions of a Bitcoin and these can go as far as eight decimal places.
Gold can also be used as a unit of account as it is also divisible (although less easily). Its value can be related to other goods through its value per ounce in a given currency.
Store of Value
Store of value refers to an asset that can be set aside for future use. As it can be used in the future, it is believed to hold value overtime, as opposed to perishable goods such as milk, which is a poor store of value due to its propensity to spoil.
Sceptics of Bitcoin argue that the cryptocurrency has no value and is merely worth what the next person is prepared to pay for it. Some also believe that the fact that you cannot physically touch it is consequential when ascertaining its store of value.
In conclusion, it can be argued that while Bitcoin has been used as a medium of exchange, neither Bitcoin nor gold meet all three functions necessary to be considered ‘money’ and therefore neither fully satisfies a utility as currency.
Bitcoin and gold share few similarities, so their differences are not to be overlooked, particularly from a trading point of view. Gold is still regarded as a safe haven, while Bitcoin is renowned for being a particularly volatile asset. Greater volatility brings with it a need for greater risk management in the form of position sizing and well-defined stop and take-profit levels.

It's Time to Let Everyone in on Litecoin's Biggest Secret

Fellow Consumers,
It's possible that you might be getting a little upset at the current BTC fees. Please assist me in sending, or editing as you see fit, this drafted outline and email to whichever business you feel would benefit from using Litecoin instead. Or you can make a video, or tweet the link, or 100 other things. Just help in bringing attention to Litecoin in BTC's mempool time of need. It's time they learned Litecoin's biggest secret .... It’s THE BEST payment method out there. Also, please support businesses that currently accept Litecoin. I've put together a list below the draft.
........................................................................................................................................
BEGIN EMAIL DRAFT
To whom it may concern,
Has your company ever considered receiving the alternative payment currency Litecoin?
To begin, you may already be accepting bitcoin and Litecoin is very similar to bitcoin. If you're unfamiliar with bitcoin as a currency then Litecoin is a great place to start. They are even built from the same Core coding. A benefit to Litecoin is that it has a 2.5 minute block time instead of bitcoin's 10 minutes. This makes Litecoin's transaction speed four times faster and much less expensive than bitcoin. In layman's terms, this just means payment is confirmed faster and less expensively with Litecoin.
For reference - you can see the average fee of both bitcoin and Litecoin in US Dollars compared here: https://bitinfocharts.com/comparison/transactionfees-btc-ltc.html#1y
This chart shows the average fee for Litecoin is staying around 10 to 20 cents, and bitcoin bouncing between a low of $1.50 and $8.00 recently. This means you would pay less in fees to convert the same total value into fiat or USD in this case.
If you were to compare this to the average credit card transaction fees, of say 2.5%, any transaction over $5.00 would be more profitable through Litecoin.
Reference of fees found here: https://www.cardfellow.com/average-fees-for-credit-card-processing/#Typical
If you've heard of Litecoin, I'm sure you have heard the saying "Litecoin is the silver to bitcoin's gold." But really, Litecoin should really be considered Platinum instead of silver. Platinum is stronger, more durable, and much more ductile. Over 20% of all consumer goods either contain platinum or are produced using platinum. Platinum is truly an enduring metal just as Litecoin is truly an enduring cryptocurrency. It will be 6 years old this October, bitcoin is 8 years old.
A few facts that demonstrate Litecoin's strength, durability, and ductility are listed below:
  1. Litecoin has a large economy and your current bitcoin technology should work on Litecoin with very little changes. If you don't use bitcoin, it is still easy to implement.
  2. Litecoin has the best combination of economic size and technical similarity to bitcoin than any other cryptocurrencies.
  3. Litecoin is capable of eight times as many transactions as bitcoin in a ten minute period.
  4. Litecoin has much faster confirmation times with blocks that are not full.
  5. Litecoin has proven its longevity compared to many other cryptocurrencies that have come and gone.
  6. Also, if changes ever need to be made to Litecoin, it doesn't take years to implement them. Litecoin implemented Segregated Witness before bitcoin, and will most likely run on the lightning network before bitcoin as well. If you don't deal with bitcoin, this all just means Litecoin is a front runner in implementing new technology and features.
  7. Litecoin is a limited supply coin, launched fairly, with no coins premined (no developer is hiding a majority somewhere), nor has it ever hard forked for any special interest groups. It is decentralized and no one person or group controls what happens to it and no one person or group can manipulate the market.
  8. Whole Litecoins are much more affordable than whole bitcoins. This helps eliminate some psychological barriers to entering the market.
In conclusion:
If your company was to accept Litecoin, I would be happy to start conducting my business with you.
If your company accepts bitcoin payments but not Litecoin, I hope I have helped shed some light on the benefits Litecoin could bring to your business.
If your business does not accept bitcoin payments, I hope I have introduced you to an alternative payment option that a large number of people transact with everyday who would love to add you to their list of merchants accepting Litecoin. It really is the currency of the future.
If you have any questions about Litecoin or need help in possibly implementing Litecoin into your business, please let us know. There are many of us here excited to help you transition into accepting Litecoin or to help you further and answer any questions you may have.

For those who don't know, Gyft.com & eGifter.com sell gift cards online (Amazon, iTunes, BedBathBeyond, etc., like you see in the revolving rack at the corner convenience store). Both services accept BitcoinCash (via Bitpay). Instead of a plastic card, they send you a "virtual" card (an activation code). So you can buy stuff from all the stores above with BCH (& then replace your BCH so you don't later feel like you spent $500 on diapers :)
I scraped and massaged the lists from both services for you because I find it easier to refer to than browsing their sites that make you scroll through logos instead.
Many of the retailers are found on both services. Many are unique to one. The superset is probably about 300 (plus thousands of local restaurants that participate with Uber Eats).
There's a lot more than Restaurants, Starbucks & Playstore! You'll find Uber, airlines (Southwest, American, Delta), Hotels.com, XBOX, Playstation, Dell, Microsoft Office, Hulu, Ebay, Wine.com, Walmart, Target, Home Depot, CVS Pharmacy, Marshalls, Panera, Nordstrom Rack, Nike, Adidas, Zappo, Foot Locker... You can literally live on BCH now (if only there were a way to pay utilities and rent/mortgage).
You can have a super smooth experience buying a card while queuing for the register. When you tap to pay in BitcoinCash (or BTC) from the Gyft app, android prompts you to launch your wallet! The amount, fee, and receiving address is already filled in. Simply take a look to confirm and then slide to pay. In seconds (before the next register is open) the new gift card is in your Gyft app "wallet" and ready to be scanned by the cashier. You can also regift/send the gift card to a friend instead of activating/revealing the card's code.
Note that Uber credit is how you pay for Uber Eats, so an Uber gift card can not only get you around town but also bring food to your door from restaurants in your neighborhood.
Feel free to paste the lists into the weekly/monthly or any BCH updates, or to categorize it (i should have but I don't know them all). It's not my data obviously. I don't know how often the two services update the lists.
(Not sure which are limited to regions. I can confirm that Uber gift card was credited when pasted in the Uber app, in Japan, but wasn't usable for rides in Japan. The balance was perfectly usable later, in USA.)

[uncensored-r/Bitcoin] /r/Bitcoin FAQ - Newcomers please read

The following post by BinaryResult is being replicated because some comments within the post(but not the post itself) have been silently removed.

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 lots of additional video resources check out 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.
  • 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.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin 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.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or 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.
  • 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. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
  • If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
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, usually from a text message or app, 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.

There are also lots of charities which accept bitcoin donations, such as Wikipedia, Red Cross, Amnesty International, United Way, ACLU and the EFF. You can find a longer list here.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
  • 1-3% savings over credit cards or PayPal.
  • No chargebacks (final settlement in 10 minutes as opposed to 3+ months).
  • Accept business from a global customer base.
  • Increased privacy.
  • Convert 100% of the sale to the currency of your choice for deposit to your account, or choose to keep a percentage of the sale in bitcoin if you wish to begin accumulating it.
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, 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 crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.

Just like any other form of money, you can also earn bitcoins by being paid to do a job.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin ?BTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (?L) or micrometre (?m)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
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:
  • 0.02 BTC
  • 20 mBTC
  • 20,000 bits

40 Bitcoin Predictions: What I got right, what I got wrong, and ones for the future

I think you all might be interested in reading about Bitcoin predictions - and hopefully sharing some of your own - so I've posted the intro + the 4 predictions that are viewable at no cost. And if you're enticed enough, the following 36 can be viewed on Yours.org for a measly $1.25. Hope you find them interesting.
https://www.yours.org/content/40-bitcoin-predictions--what-i-got-right--what-i-got-wrong--and-ones-f-ee169b2821c6
During the middle of 2013, I discovered Bitcoin as a result of what was going in the country of Cyprus, and let’s just say, I've been hooked ever since. Like most people, I've made many predictions over the course of Bitcoin’s history, and in this writing, I'm going to share as many as my memory allows. You should see some bonehead predictions, some spot-ons, and some that are too close to call. The predictions will go in chronological order, beginning with the initial predictions made in mid-2013, and ending with ones of the future. Four are viewable at no cost, and the remaining 36 can be viewed by unlocking the paywall for a cool, $1.25. And if you share one of your own in the comments section, I will gladly send $0.25 back in your direction. Hope you find the predictions interesting and the stories behind them equally as enjoyable. Now let’s get this show on the road.
Prediction #25: In the midst of another “China bans Bitcoin” episode, the bull market would NOT end.
Result: True. I was proud to get this one right, because at the time, a lot of people I knew were freaking out, thinking this was the end. I stood calm, knowing this storm would pass, knowing sunny days were just ahead. I knew this because the chart wasn’t going to end with Bitcoin topping out at $5,000. Not when we had just broken out over $3,000. Not without rising exponentially. And mostly, because we had experience with “China banning Bitcoin” back at the beginning of 2017. When it happened then, Bitcoin’s price fell, but it didn’t break. It recovered, and a few months later we proceeded to reach the high from 2013, which then launched us into the beginning of Bitcoin’s meteoric rise. It didn’t stop us then, and it wasn’t going to stop us now. I told my friends there wasn’t anything to worry about, and it would probably be a good time to buy if they had any extra cash lying around. China banning Bitcoin is never as scary as it seems.
Prediction #16: Vinny Lingham’s “Bitcoin to $1,000 by 2017” prediction was going to be accurate.
Result: True. Just as Vinny publicly predicted, the price of Bitcoin was $1,000 as 2017 began. Because of this prediction, he became known as the Bitcoin Oracle; but to me, he was somebody who knew how to read and interpret a chart’s pattern correctly and extrapolate the data from it. That may sound like a knock on the guy, but I hope you don’t take it like that. He’s a very intelligent and respectable person. I value his opinion, appreciate his Bitcoin contributions with Gyft, look forward to him making a difference in identity verification with Civic; and to be honest, it did take talent to make that prediction. But I watched The Matrix, so throwing “Oracle” around is something I don’t take very lightly. Haha, just kidding around. But anyways, based on the trend at the time, his prediction seemed accurate and I absolutely agreed with it.
Prediction #17: After the Winklevoss Bitcoin ETF (Exchange Traded Fund) was disapproved by the SEC, it was curtains for the price.
Result: DEAD Wrong. - And I’m so glad I was… But wow, this event put me through one hell of an emotional rollercoaster. I was so hyped up from it, tracking the price on a daily basis, watching industry news, writing articles; and then on the day the ETF was axed, my enthusiasm was gone, hopes were shattered, and I was in one of the worst moods I’ve ever had in my life. I didn’t know what to do, what to think, or where the market was going to go from there. 2013’s all-time high had already been breached – largely due to the ETF speculation – so I fully expected the ETF to be approved (wishful thinking). When this thought was put to rest, and because the run-up past 2013’s all-time high seemed to be the catalyst for the rise, I began to doubt whether the exponential rise would ever occur again. I fully expected the price to tank. Well, I was both right and wrong. For the first few days, it held strong, but after a few more, it started to drop. As it did, my emotions got the best of me and I ended up panic-selling some of my small stake like a worried little child. What a costly error that was…
Future Prediction #5: Central Banks will issue their own digital currencies.
Comments: And I say GOOD. Let them get their citizens accustomed to using digital currency. Let their centralized cryptocurrencies compete with decentralized cryptocurrencies. Governments and central banks are powerless to stop the best decentralized cryptocurrency(s), and they may temporarily “win” by disallowing trading or commerce to be conducted with them, but as the age of digital money makes its mark on the world, the best form(s) of money will win out in the end. The good ones will always be available as an alternative for the inevitable day when the central bank or government abuses their money-issuing rights. When they’ve gone too far and the citizens unite and stand up to them, the people will have a fair alternative to fall back on. Decentralized cryptocurrencies can, and will, keep governments in check - and you should consider that a prediction, too.

We play white elephant during Xmas party at my work....about 100 or so people attend it. This is what I'm planning to give. (TEXT VERSION) Feel free to copy and use it.

Pic
Inside this envelope is a paper that holds Bitcoins.
Bitcoin(abv. BTC) is digital currency that is worth real money (At the time of writing this, each BTC is worth about $726). It's the first decentralized electronic currency not controlled by a single organization or government. It's an open source project, and it is used by millions people. All over the world people are trading millions of dollars worth of bitcoin every day with no middle man and no credit card companies. It's a startup currency which has never happened before.
Email let us send letters for free, anywhere in the world. Skype lets us make phone and video calls for free, anywhere in the world. Now there's bitcoin. Bitcoin lets you send money to anyone online, anywhere in the world for less than a cent per transaction! Bitcoin is a community run system not controlled by any bank or government. There's no wall-street banker getting rich by standing between you and the people you want to send and receive money from.
It is impossible to make a counterfeit Bitcoin and there will only be a finite number ever created. No one person controls Bitcoin and therefore no one can control what you do with Bitcoin. All of these qualities add up to make Bitcoin a solid platform for both saving and spending money.
Like gold, oil, or any other fiat currency, Bitcoin value also fluctuates every second mostly because of demand and supply. At the beginning of this year each BTC was worth $14 then it went upto $1200 during Thanks Giving and at time of writing this it is worth $726. You can see the realtime value of your Bitcoins at http://coinbase.com/charts - the number in the top right is the current value in US Dollars, that is the price that people are actively buying Bitcoins for right now on an exchange market.
What can you do with Bitcoins? *You can send them to people. You can setup an online ‘wallet’ at http://coinbase.com and send them to anyone in the world for free.
You can buy things. *http://www.gyft.com/ Shop for gift cards and pay with BTC *http://www.bitcoinstore.com - Buy electronics. *http://coinkite.com - Bitcoin debit card.
You can hold onto them as an investment. *Just put this card away somewhere safe, and in a few years’ time you may be surprised at the value that your Bitcoins accrue. Who knows this paper might worth thousands of dollars in near future.
You can convert them back to US Dollars at any time. *http://coinbase.com allows you to buy and sell Bitcoins and withdraw or deposit US dollars back into your bank account.
If you’d like to know even more, go to http://weusecoins.com or http://bitcoin.it
Bitcoin is going to be the biggest opportunity for innovation that the world has seen since the industrial revolution.
HAPPY HOLIDAYS

/r/oBitcoin FAQ - Novatos por favor leiam

Bem vindo ao /oBitcoin FAQ fixada

O texto que se encontra aqui foi desenvolvido por Mtzrkov e outros em Github.com/btcbrdev/oBitcoin e está em domínio público para ser usado livremente por qualquer um.

O que é bitcoin?

Bitcoin (BTC ou XBT) é o primeiro e mais importante dinheiro eletrônico sem autoridade central, baseado numa tecnologia open-source inédita chamada Blockchain, que foi desenvolvida por Satoshi Nakamoto em janeiro de 2009. Essa tecnologia permite a criação de um "banco de dados" confiável P2P (ponto-a-ponto), o que abre caminho para muitos tipos de inovação, sendo uma delas o próprio bitcoin e outras como contratos descentralizados, por exemplo.
Nota: normalmente emprega-se "Bitcoin" em maiúsculo para se referir ao protocolo (baseado na tecnologia Blockchain) e em minúsculo "bitcoin" para se referir a uma unidade da moeda.
O Bitcoin, além de um bem digital, pode ser considerado também um sistema de pagamento, totalmente independente de qualquer sistema já existente, como cartões de crédito, Paypal, bancos e outros. Sua capacidade atual estimada é de 7 transações por segundo, mas essa capacidade pode ser aumentada com o passar do tempo se houver necessidade. Por ser puramente digital e distribuído, o Bitcoin funciona 24/7 e tem alcance mundial, além de ter locais especializados de troca pela moeda local (chamados exchange) nas principais cidades do mundo.
A segurança da rede do Bitcoin, ou seja, o que garante que não existirá um chamado "gasto duplo" do mesmo dinheiro, é o consenso da rede P2P feito pela validação das transações por parte dos mineradores. Para que um minerador consiga incluir um bloco válido na rede, ele precisa utilizar um grande poder computacional. O processo de mineração consiste na realização de cálculos matemáticos para a seleção de quais transações válidas serão incluídas no próximo novo bloco do Blockchain, excluindo aquelas que tiveram uma tentativa de "gasto duplo" naquele período. Cada nó da rede, além dos mineradores, também é capaz de verificar a validade das transações incluídas no bloco. É nesse processo também que aparecem os "bitcoins ainda não descobertos". A distribuição dos bitcoins é feita de forma previsível, tendo uma queda de recompensa pela metade de 4 em 4 anos. Serão encontrados no máximo 21 milhões de unidades da moeda.

Quanto vale um bitcoin?

O preço de mercado de um bitcoin é determinado através da lei da oferta e da procura, portanto estando sujeito a variações de preço por causa de acontecimentos políticos e econômicos (como desvalorização e inflação de moedas estatais, conflitos, maior demanda por Bitcoin etc).
Assim como nas moedas estatais, o preço do bitcoin varia e pode ser diferente dependendo do lugar em que for negociado.
Se você for comprar dólares no Brasil, você terá que procurar uma casa de câmbio que poderá ter a cotação de R$ 3,00 por dólar, por exemplo. Caso vá a outra casa de câmbio, você poderá notar que o preço poderá ser ligeiramente diferente, além das taxas também variarem. Com o Bitcoin não é diferente. Essa variação entre as exchanges (nome comumente usado para se refererir aos locais de compra e venda de bitcoin) são equilibradas pelo mercado através de operações de arbitragem (comprar num lugar mais barato e vender num mais caro).
Para se ter uma ideia do preço médio do bitcoin, você pode dar uma olhada em sites como os que seguem:
Para um gráfico do preço ao longo do tempo, acesse:

Volatilidade

Por ser uma moeda ainda muito recente (inventada em jan/2009) e ainda não muito utilizada, seu preço de mercado ainda é muito volátil. Isso faz do bitcoin um investimento de risco atualmente. O preço tende a ficar mais estável ao longo do tempo, quando o mercado puder definir com mais exatidão seu "preço real". As oscilações também tendem a diminuir conforme o seu market cap (quantidade de moedas x preço) aumentar. Hoje (2015) o market cap do bitcoin é de US$ 3 bi, o que pode ser considerado pouco se comparado ao valor de algumas empresas como a Dell (US$ 24 bi) ou ainda de outras commodities como o ouro (US$ 2.600 bi).

Como obter bitcoins?

O bitcoin é um bem digital e assim como outros bens, pode ser adquirido de diversas formas:

1. Negociação direta (P2P / pessoa a pessoa)

Uma das maneiras mais baratas de se negociar bitcoins, porque não tem taxas, é comprando diretamente de outras pessoas que já possuem a moeda. As duas partes chegam a um acordo de preço e a troca é feita. Geralmente quem tem menos reputação entrega o bitcoin ou a moeda local primeiro.
Por ser uma maneira relativamente arriscada, pois não há um mediador para casos de descumprimento de uma das partes, a reputação de alguém deve ser muito considerada. Exemplo: prefira negociar com alguém do seu círculo de amizades (rede de confiança), alguém que você confie muito como familiares e amigos, ou por uma indicação (amigo de amigo). Se a outra parte tem uma reputação duvidosa, prefira negociar aos poucos (divida os valores em várias partes menores e vá trocando aos poucos).
Algumas ferramentas auxiliam nesse processo de reputação e rede de confiança, sendo elas:

2. Negociação indireta (com intermediário)

Outra forma de se negociar bitcoins (e essa provavelmente é a maneira mais conveniente, embora não seja a mais barata) é utilizando um intermediário que viabilize a compra e venda de bitcoins entre pessoas interessadas. Esses intermediários são as "corretoras" ou "bolsas" de bitcoins (mais conhecidas por exchanges).
Essas corretoras fornecem um serviço de intermediação entre compradores e vendedores de bitcoin, cobrando uma taxa para tal. Por causa disso o bitcoin nas corretoras tem um preço final um pouco mais alto do que se fosse comprar de outras maneiras, mas devido ao altíssimo volume, uma operação pode ser realizada instantaneamente.
Além de usar exchanges, você também pode encontrar um intermediário na relação P2P, tornando-a mais segura. Exemplo: um amigo em comum, que pode levar uma comissão previamente combinada para intermediar as duas partes.
Você pode conferir uma lista de corretoras no ExchangeWar. Algumas das principais corretoras brasileiras são:

Onde gastar bitcoins?

Hoje é virtualmente possível gastar os bitcoins em qualquer lugar, usando algum intermediário para trocá-los imediatamente sob demanda por alguma moeda local, como numa exchange ou com serviços como Neteller, Xapo ou Gyft.
Alguns locais porém já aceitam a moeda digital diretamente, como é o caso da Microsoft, Dell e Overstock, além de inúmeras outras ao redor do mundo.
Confira uma lista com mais de 100 mil lugares que já aceitam diretamente o bitcoin em SpendBitcoins ou no CoinMap.
Segue algumas listas de locais que aceitam bitcoin no Brasil:

Como minerar bitcoins?

Para minerar bitcoins você precisa executar um software em um computador especializado (ASIC) que possa realizar uma grande quantidade de operações matemáticas demandada pelo sistema de consenso P2P do bitcoin.
Logo após a criação do Bitcoin em 2009, era possível e rentável minerar bitcoins utilizando o processamento de computadores pessoais (através de simples processadores e placas de vídeo), mas com o tempo essa atividade deixou de ser rentável e tornou-se praticamente impossível para tais máquinas. Isso aconteceu pois o interesse no Bitcoin aumentou muito, trazendo assim mais pessoas para a mineração e impulsionando uma corrida por maior quantidade de processamento. Com o avanço da tecnologia e o aumento do interesse por Bitcoin, mais poder de processamento foi adicionado à rede Bitcoin e isso resultou em um aumento da dificuldade para se encontrar novos Blocos.
Essa é uma característica do protocolo Bitcoin: quanto maior o poder de processamento da rede, maior a dificuldade para se minerar bitcoins - ou seja, maior a dificuldade para se descobrir novos Blocos. Um bloco é um arquivo que possui uma identificação (data, hora e informações genéricas) e um registro das transações (movimentação de bitcoins entre endereços) mais recentes. Resumidamente, os mineradores são uma forma de manter a rede Bitcoin segura e operante, algo que demanda muito poder de processamento (o que torna inviável o uso computadores de propósito geral para tal fim) e que, como retribuição por essa tarefa importante, gera uma recompensa em bitcoins pelo trabalho.
Todas as transações, ou seja, as movimentações em bitcoins realizadas entre endereços (carteiras), são anônimas pois se caracterizam como uma transferência de fundos de um endereço Bitcoin para outro, que, embora tenham relação indireta com pessoas reais, não possuem uma relação direta. Ou seja, não é possível dizer com absoluta certeza que determinada pessoa é detentora de um endereço a menos que ela diga isso em algum lugar - o que torna o Bitcoin algo pseudônimo, não anônimo (você é anônimo apenas se quiser e tiver conhecimentos para tal). Todas as transações da história da rede Bitcoin são públicas e podem ser conferidas em sites como o Blockchain Info.
Então...é impossível minerar hoje em dia num PC comum ou notebook? Sim, mas não é lucrativo. Para isso existem os ASICs (Circuitos Integrados de Aplicação Específica, em inglês Application Specific Integrated Circuits), hardwares específicos para mineração. Há uma lista na Bitcoin Wiki, em inglês, onde estão listados todos os ASICs disponíveis no mercado e também placas gráficas e processadores. É importante notar que embora seja possível minerar bitcoins, não é algo recomendado aos brasileiros, uma vez que o equipamento é caro, importado e possui taxas de importação - além da energia elétrica brasileira, que inviabiliza totalmente o processo.
Nota: Em processo de desenvolvimento: Guardando seus bitcoins e Ganhando bitcoins.

My father, an early (Nov'12, $13.35) investor like me, asked what all the hubbub was about with people spouting "Verge of Collapse", this was my response.

'Verge of collapse' is a scare tactic to insight chaos sells to drive the price of bitcoin down. it is a manipulation trading tactic that due to bitcoin's 'wild west' tendencies isn't illegal...yet. This mass amount of sells will allow people to purchase a lot of bitcoin at a lower price, and then when they're done with that and want to drive the price up....media manipulation and sensory saturation of the digital commodity will do just that.
Those that are running away with their tails between their legs were never in it for the long run anyway. They saw it only as an investment to flip and not for what it truly is, which is financial freedom.
Bitcoin will always be on people's minds in that its made an impression. The idea makes obvious sense...its my money and I want to use it how I want, when I want, and with out fees or regulations, but there are those in old institutions that like to deal blows...and sometimes they hurt.
This Mt. Gox scandal; however, was due to incompetence in the Tokyo office and liars stealing bitcoins with fake id numbers. When this news broke out the community didn't rush to run away or get scared, because we've grown strong. It was the exact opposite we claimed Mt. Gox as the perpetrator and casted them out of the communities and took their charts off our websites. Mark Karpeles was forced to step down from the Bitcoin Foundation as people protested outside of Mt. Gox in Tokyo on Feb. 14. It absolutely was a real debacle; however, with the disbanding of Mt. Gox the Bitcoin community and the price of Bitcoin has returned to its normal graphs.
Ups and downs will continue and with growing interest obviously government will be involved, but if investors want to continue flipping their initial capital through banks thats really the only route the community can take.
The best thing about all of this is that the websites set up to take bitcoin for goods and services such as gyft.com and overstock.com just to name the big players haven't backed down and still continue to take Bitcoin on an hourly basis generating tens of thousands of transactions a day. Thats what is keeping this digital commodity in its roots.
tl;dr (toolong;didn'tread): Bitcoin isn't going anywhere near its grave anytime soon, and if it ever does it is because an even better form of transaction process has been invented and implemented widely throughout the world; however, i am almost 100% positive that if such thing occurs Bitcoin will be the basis at which it is born.

4/17/14 Video News - Bitcoin.com, SecondMarket, Walmart, Ron Paul & Dogecon SF

Video: http://www.moneyandtech.com/apr17-news-update/
Catch up with today's top news stories in Money & Tech:
Blockchain.info announced today that it has struck a five year deal to exclusively manage the domain Bitcoin.com. The domain's sleek new homepage now features three main links for the Blockchain wallet service, Zeroblock news and charts, as well as a search function to explore the rest of Blockchain.info. As stated in their announcement, this is part of the mission quote "to create new learning experiences and introduce millions of users to Bitcoin."
SecondMarket has taken another step towards the ultimate launch of America’s first fully regulated Bitcoin Exchange, releasing a new website for their quote “Experienced, Full Service Bitcoin Trading Services”. CEO Barry Silbert says he hopes to launch the fully licensed exchange for all compliant users this summer.
Walmart has announced the April 24th launch of their new Walmart-2-Walmart Money Transfer Service, in partnership with global remittances company Ria, which could clarify their decision to cut ties with Gyft.com. The new low-cost service will allow customers to transfer money between the over 4,000 Walmart stores nationwide, and is aimed at helping the almost 28 percent of Americans who are either underbanked or unbanked and rely on money transfers.
ZaZZZ, billed as the first Marijuana vending machine in the US, will also be accepting bitcoin. Since the legalization of marijuana in 2012, Bitcoin has become popular among dispensary owners who have been rejected by traditional financial institutions. The ZaZZZ machine however is far from an anonymous way to buy the newly legal drug, as it is equiped with an ID reader, and a video camera.
Former Congressman Ron Paul took to popular question-and-answer website Quora to express his thoughts about bitcoin, saying "Though I don’t personally believe that Bitcoin is true money, it should be perfectly legal and there should be no restrictions on it... For this to operate, we need to have freedom from government intervention when it comes to the Internet."
Dogecoin creator Jackson Palmer and the Dogecoin Foundation are putting together Dogecon SF on April 25th in San Francisco, in partnership with Follow The Coin. The event’s organizers expect it to be the largest dogecoin gathering yet, lining up celebrity speakers such as litecoin creator Charlie Lee, Doge tip bot co-founder David Dvorak, and bitcoin evangelist Andreas Antonopoulos.
We continue bringing you interviews from the recent Inside Bitcoins New York conference today with BitAngels Managing Director David Johnston, and BitGo CEO Will O’Brien. Watch those, and then enjoy the official trailer for the bitcoin documentary, The Rise And Rise Of Bitcoin, which premieres at the Tribeca film festival next week.
