The total amount of bitcoin is hardcoded to be less than 21 million BTC . . .
FTFY
-snip-
I was wondering when you would show up to correct all those wrong answers

to "defend" my own post:
The total amount of bitcoin is hardcoded to be 21 million BTC at max.
The hardcoded limit is defined [1] as exactly 21 million in MAX_MONEY. While -due to the nature of the halfing- this might never be reached, its still the limit. Thus my wording of "almost" 21 million in the next sentence.
