user57488: I don't get how there's a limited supply of 21 million bitcoin if we can go into the infinite amount of decimal places. 
So for example, you can't go less then 1 cent if we take USD. in BTC, you can have 0.00000001 or however many zeros after the point, not sure but I would assume it's alot. So isn't there alot more than 21 million bitcoins, if we take in decimals into account?

user11253: You can't go into an "infinite" amount of decimal places. The smallest unit of Bitcoin is the satoshi, which is 0.00000001 bitcoin.
There will be a total of 2100000000000000 satoshi.
