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.

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".

Publicnote Bitcoin Treasure Hunt 2 (0.01337 BTC)

Time for another quick round. One private key hodling 0.01337 BTC has been placed into a note at publicnote.com.
To find the private key, you must enter the correct title. Find it, and it's yours to keep.

Here’s your clue: 1FXYAEwj2Ckm5EdWnGPEPg==

Prize: https://www.blockchain.com/btc/address/1CEeC4zJp5z2todhd5tteCvCLnSzmdvbs5
Additional clues are planted all over publicnote. Participants are welcome to modify clues or plant new ones to throw others off. I will be updating clues as well.
To prove that this contest is real, the bitcoin address was generated using the correct title as the seed to a brainwallet, with "publicnote" as the salt. The solution will be published after the prize is claimed. There is no time limit.
Have fun!

Congrats to mooncritic for solving the puzzle! The correct answer was:

The danger is if people are buying bitcoins in the expectation that the price will go up, and the resulting increased demand is what is driving the price up. That is the definition of a BUBBLE, and as we all know, bubbles burst.

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 μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
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:

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.
Google Auth Authy
Android Android
iOS iOS

Brainwallet puzzle - 0.04 BTC reward

Instructions
I have placed 0.04 BTC (it was going to be 0.05 BTC so the prize would be around $300, but with the recent price rises, I edited accordingly) in the following address:
1E3NARnUX25UgMvZd5EZTutD9yVHTVGDNC
Here’s how you get it:
I have created a series of puzzles / riddles that sometimes require only one or two steps in logic, and sometimes require multiple steps in logic. The puzzles span vast areas of trivia, drawing from different corners of knowledge. A lot of this just involves following detailed (and sometimes undetailed) instructions.
The below puzzles will yield a single American English word or a single number as their solution. Take the answer to each puzzle (besides the last two) and put them IN ORDER into brainwallet.io with a single space between each answer (and no space at the end of the last clue).
BrainWallet is case sensitive. So only lowercase letters will be used. There will be no uppercase letters used. No punctuation is used, even in numbers. No answers will have spaces within that answer.
Take the final two answers for the last 2 puzzles (puzzles 11 and 12) and use them as “salt” in the “generic” tab of brainwallet. Make sure that those final two answers are separated by one space and that there is no space after the second answer. Hit “generate”.
If the brainwallet displays a public key different from the one above, check to make sure you don’t have any extra spaces anywhere. If your formatting is correct, then you have one or more incorrect answers.
If you see the same wallet address as above, you have solved it correctly. Take the private key brainwallet displays for you and import it into the bitcoin wallet client of your choice. Going to blockchain.info could be the easiest thing. (sign up for an account there, then open your account and find the import/export feature. They’ll ask for the private key to be imported. Paste the private key, and then you can then “sweep” the funds out of the puzzle’s wallet and into your own wallet.)
Please comment as you feel appropriate below. I will answer technical/logistical questions and might throw out some hints or clarifications about the clues if I feel insight is warranted. If and when you are successful, please comment below to boast of your victory and let everyone know you are a real person and I didn’t just take my bitcoin back. Also, tell us what you’ll spend the money on or if you’ll just HODL.
Clues 1) 33 37 2e 37 34 39 33 35 34 20 2d 31 32 32 2e 33 38 39 39 35 36 20 77 68 61 74 20 61 72 65 20 74 68 65 79 20 73 65 6c 6c 69 6e 67 20 28 68 6f 6f 73 69 65 72 20 73 74 72 65 65 74 29
2) sopranos.reframed.snubbed - what country? Find the right tool (could be helpful to consider what is being input and what the desired output is).
3) 1/2 Beyonce's [approx. 2pi - 0.28]th studio album, 1/2 law and order actoactress, [the first night playing at USSR closed (on opposite day)] - what else happened? sum the four numerical freeways.
4) Of the four inter-galactic governors, on the order of 246, the answer to this puzzle is married to the weak one. (use the adjective form)
5) The same both forwards and backwards, this character is the O.G. when it comes to behaving badly.
6) Most elderly player to hit a ball out of the park with the bases loaded (MLB) what is their home country? Take total square miles of said country (per Wikipedia) identify the prime factorization of that number sum those factors multiply that result by the year I was born to get your final answer.
7) Upon this day (of the launch of the puzzle) after subtracting 138 from the largest unit of time generally used, a really cool thing happened. Take the identifying, official number from that event, and subtract from it the telephone area code of the place where the other thing ($) that happened that day happened.
8) Relativity. Princeton. He had a teacher. Teacher died in 1909. Teacher had a thing named after him. Go to the very bottom of the Wikipedia page for that particular thing. Not the very bottom but close to it. There is a number down there. 8 digits, including one dash. Remove the smallest digit. Remove the dash. 74616b65796f75726173736f6e6f766572746f77696b6964617461. The answer is the coordinate data from the resulting entry without any punctuation (use only the digits. In order.)
9) The place that darkness fears the most, Causing orgs to hold their secrets close, Supported by crypto, Founder must tiptoe, As he collects more things to post.
10) Seven individuals, Alaina, Azalea, Alexandra, Augustine, Atticus, Anastasiya, and Alexander, all stand in a straight line, all facing the same direction. Atticus and Azalea have exactly two people between them. Azalea and Alaina are not at the front of the line. Atticus is further ahead in the line than Anastasiya. Alexander has one person in between he and Anastasiya. Augustine is one spot away from either the front or the back of the line. Azalea is directly next to Alaina. Atticus is directly in the middle of the line. Identify the order of the individuals from the front of the line to the back, then take the names of the people in order and convert every letter to their corresponding numerical value in the alphabet (A=1, B=2…Z=26). The answer to this puzzle is all of the numerical values without any spaces between them in the order of their places in line. (AKA, the answer will be a loooonng continuous string of numbers.)
11) 1834: a1 a2 a3 b1 b3 b7 c2 c3 d6 f8 h6 Name the non-Frenchman.
12) Purchase 2 dripping, succulent, sopping pieces of land meat for this number of U.S. dollars.
EDIT: Please refrain from posting direct answers. Glad this is taking off. Also, if you post one of the clues in another subreddit, please link to this post so other people know what they’re doing the work for.
EDIT 2: Solved and prize claimed! If you liked this, please subscribe to this sub and donate to future puzzles at 18no9TMRswUaHbi4ecBPjrPEa2KAckaCmH. I️ want to make this a thing. And I️ want to make future ones more difficult.

/r/Bitcoin FAQ - Newcomers please read

Welcome to Bitcoin!

Maybe you're here because you've received a tip on social media or from /FreeBits, 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 is a useful site 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. Top recommendations include:
US & Europe
China
Also exchanges such as those listed below can be used with bank transfer in most of Europe and US
For even more bitcoin exchanges by country location, review these exchange country listings.

Where can I spend Bitcoins?

A comprehensive list can be found at TheBitcoinPage.com but some of the key ones are below:
There are also lots of charities which accept bitcoin donations, such as Wikipedia 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.

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.

Tipping

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. There's lots of discussion about which unit is the most appropriate so you might see people using different ones until people agree:
Unit Value Info
mBitcoin / mBTC 1,000 in a bitcoin SI unit for milli i.e. millilitre (ml) or millimeter (mm)
μBitcoin / μBTC 1,000,000 in a bitcoin SI unit for micro i.e microlitre (μl) or micrometre (μm)
bits 1,000,000 in a bitcoin Colloquial term with the same value as μBTC
Satoshi 100,000,000 in a bitcoin The smallest unit of bitcoin, named after the inventor
For example, assuming an exchange rate of $500 for one Bitcoin, a $10 meal would equal:
Assuming the worth of bitcoin continues to increase, it will become easier to work at these lower divisions in day to day life.

Can we get back to actually discussing Bitcoin rather than the exchange rate of Bitcoin?

I know this a bit circle-jerky, but I really don't care too much what the current price of BTC is. I'm holding for now. Really the only thing that will make me sell is if I see another cryptocurrency or equally brilliant piece of software that makes the featureset of bitcoin look antiquated. I don't see that happening very soon though. Some of you newbies are speculating on something you really don't even know the utility of.
By featureset I mean this.
  1. Distributed, verifiable ledger: The blockchain is really a fancy name for a extremely secure ledger. It contains a record of every transaction that has occurred in the bitcoin ecosystem. This is an amazing achievement on its own. Can you imagine if the company you worked for had a system setup that kept track of all this information this reliably?
  2. The ability to memorize a number (or brainwallet phrase), walk across a border and (provided their there is a local exchange) change your money back to whatever fiat currency is the accepted medium of exchange in that country.
  3. The ability to have at-a-glance, verifiable, data about the entire bitcoin ecosystem. Statistical analysis is so much easier when you know your source data is accurate. http://blockchain.info/charts
  4. We know, with almost certainty, how many bitcoins will have been created by the end of the day tomorrow, 2 weeks from now, and in the year 2140. If nothing else, this is an amazing economic experiment. We get to see what a known, controlled rate of "coin" production does to society. I personally like that knowledge.
  5. Smart contracts could in the future change the way we do business, pass money to children, pay loans, etc. https://en.bitcoin.it/wiki/Contracts
  6. Green addresses get around the double-spend problem. https://en.bitcoin.it/wiki/Green_address
  7. Merged mining and other alternative chains: "Alternative chains have been suggested as ways to implement DNS, P2P currency exchanges, SSL certificate authorities, timestamping, file storage and voting systems." Goodbye Diebold.
  8. Sending money into outer space. Ok, I'm going out there with this one, but I think it's kind of fun. https://bitcointalk.org/index.php?topic=56285.0
  9. Many other features already realized.
  10. Other features that have not been invented yet.
Sorry for the ramblings, just getting tired of the rampant, "OMG!!!1!!! $120/BTC" stuff that is going on in this place. It's the featureset that we should be selling, it's not just "internet gold" or "internet cash," it's a novel thing.
tl;dr: Money/Commodity/Exchange/whatever-you-want-to-call-it ver. 2.0
Edit: Grammar Nazi.
Edit 2: I woke up to find this on the top of the subreddit and myself two bitcents richer. I love the discussion and wish I could contribute a little more, but I'm going to work.

  • 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.

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/trans...

My repost: Can we get back to actually discussing Bitcoin rather than the exchange rate of Bitcoin?

My post from 7 months ago with a couple of additions.
Original
I know this a bit circle-jerky, but I really don't care too much what the current price of BTC is. I'm holding for now. Really the only thing that will make me sell is if I see another cryptocurrency or equally brilliant piece of software that makes the featureset of bitcoin look antiquated. I don't see that happening very soon though. Some of you newbies are speculating on something you really don't even know the utility of.
By featureset I mean this.
  1. Distributed, verifiable ledger: The blockchain is really a fancy name for a extremely secure ledger. It contains a record of every transaction that has occurred in the bitcoin ecosystem. This is an amazing achievement on its own. Can you imagine if the company you worked for had a system setup that kept track of all this information this reliably?
  2. The ability to memorize a number (or brainwallet phrase), walk across a border and (provided there is a local exchange) change your money back to whatever fiat currency is the accepted medium of exchange in that country.
  3. The ability to have at-a-glance, verifiable, data about the entire bitcoin ecosystem. Statistical analysis is so much easier when you know your source data is accurate. http://blockchain.info/charts
  4. We know, with near certainty, how many bitcoins will have been created by the end of the day tomorrow, 2 weeks from now, and in the year 2140. If nothing else, this is an amazing economic experiment. We get to see what a known, controlled rate of "coin" production does to society. I personally like that knowledge.
  5. Smart contracts could in the future change the way we do business, pass money to children, pay loans, etc. https://en.bitcoin.it/wiki/Contracts
  6. Green addresses get around the double-spend problem. https://en.bitcoin.it/wiki/Green_address
  7. Merged mining and other alternative chains: "Alternative chains have been suggested as ways to implement DNS, P2P currency exchanges, SSL certificate authorities, timestamping, file storage and voting systems." Goodbye Diebold.
  8. This is amazing - Autonomous agents video wiki link
  9. Sending money into outer space. Ok, I'm going out there with this one, but I think it's kind of fun. (Probably need "space coin" with a longer confirmation time) https://bitcointalk.org/index.php?topic=56285.0
  10. Many other features already realized.
  11. Other features that have not been invented yet.
Sorry for the ramblings, just getting tired of the rampant, "OMG!!!1!!! $300$120/BTC" stuff that is going on in this place. It's the featureset that we should be selling, it's not just "internet gold" or "internet cash," it's a novel thing.
tl;dr: Money/Commodity/Exchange/whatever-you-want-to-call-it ver. 2.0

/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:
