21 million BTC divided by 7 billion people yields .003 BTC per human. That's 1 BTC for every 333 people. There are fewer than 11.5 million addresses in use, so fewer than 11.5 million people have any BTC. There is a lot more growth to

f(f(n)) = n^2 is actually easy when you consider it restricted to 32-bit signed integers. Since it's impossible to make it work for any abs(n)>65536 (it's too big), you can reserve all those values as intermediate stopover poin
