What is a good amount to have? Is there some kind of club if you own a certain amount? Like the 21 btc club or some shit? What is average, and big pimpin?
I never go lower than 21, is that good or bad?
I own 22.5 BTC. Is that good enough?
You now own just over one-millionth of the total supply of Bitcoin ever, if you think that's an achievement for yourself then that's good for you.
I personally can't imagine ever having 22.5
BTC, so I would say that yeah, you are good. There will only ever be, at most, 1 million people that will hold more Bitcoin than you, and that would be if it was distributed equally.
Much less than 1 million will have 21 bitcoins. If you own 21 bitcoins there's probably only about 100k people with 21 bitcoins right now. In the future it will be far less.
