So I have minimal experience with computers and economics. What could go wrong?
Hahah.
Anyway I have a few questions
I got a wallet through coin base bc they gave me a dollar. I put 20 from my bank acct into it so that was fun. I do have a few questions:
Be careful about who you get your answers from. There are many inaccurate and misleading answers from some of those that have answered in this thread before me.
1. Do accounts gain interest?
Accounts at Coinbase? Not at this time. Perhaps they will offer interest bearing accounts in the future, but I don't see that happening any time soon. Since most companies that offer bitcoin accounts are not regulated, audited, or carry any form of deposit insurance, you should be extremely careful about keeping your bitcoin balance in an account with a third party. It would be much better to keep your bitcoins in your own wallet.
2. Are there really only going to be 21 million?
No. There will be less than 21 million. The exact amount that were initially expected to be created was 20,999,999.9769. However, some have been destroyed, therefore there will actually be less than that in circulation when the block subsidy finally reaches 0.
What happens when they're all mined out?
I don't quite understand the question. What happens when all the gold in the ground is mined out? When there are no new bitcoins put into circulation (somewhere around the year 2140), then people will just continue using the bitcoins that already exist. As some are lost or destroyed, as long as the demand stays the same the remaining ones will become more valuable (law of supply and demand). As such, people will use smaller and smaller fractions of a bitcoin to pay for the same value of product or service. This is the opposite of inflation (where you have to keep spending larger and larger portions of currency to purchase the same value of product or service).
3. How many have been mined so far?
Right this moment (block number 330476 is the most recent block to have been mined)?
The coin supply is limited to 18,256,650 BTC. This is based on the max subsidy per block and the block height. However the UTXO (set of all unspent outputs) is actually approximately 140 BTC less than that. Some of the difference may be due to OP_RETURN outputs (which are unspendable by protocol) having a value set. This could be accidental or intentional. Another source of lost coins is due to miners taking less than the maximum block reward which in effect "de-mines" an amount of coins equal to the difference between the allowed reward and the taken reward.
4. How does one get them besides mining?
The same way one gets anything else of value in the world:
- Provide a product and accept bitcoins in exchange.
- Provide a service and accept bitcoins in exchange.
- Beg and depend on the charity in the hearts of others.
- Scam, Con, or Steal.
- Exchange another form of money directly for bitcoins.
5. I have the idea of what a faucet is.
And you are better off because of it
A "faucet" is a scam where someone creates a website and pays you an unusably small amount of bitcoins to visit the website and see (or click on) advertisements. They then get paid by the advertisers for getting the advertisement in front of a large audience. Those being paid to visit the website are generally unaware that they will eventually need to pay a larger bitcoin transaction fee when they try to use the bitcoins that they received from the "faucet". As such, they are surprised and disappointed when they eventually discover that the total transaction fees they have to pay are larger than the total bitcoins that they received from the "faucet", making the bticoins from the faucet all but useless. Of course by they time they realize that, then operator of the "faucet" has already earned a sum of money from the advertisers from the earlier vists and no longer cares if that user never returns.
Are there any good ones?
No. Just like there are no "good" ponzi schemes, or "good" con artist scams. Sure, some people *might* occasionally come out ahead if they get lucky and are in the right place at the right time (and get out early enough, but that doesn't change the fact that it is a scam and you are better off avoiding it.
Anyway. I'm a town worker and scuba instructor in central connecticut. Any advice is appreciated.
Have you considered offering to accept bitcoins from those that pay you for SCUBA instruction?
