Don't you know that because price went from 10 to 1000, that it will go from 400 to 40000 just as easily?
And from 40,000 to 4,000,000 just as easily? Yeah, it is exactly the part I am not "getting". Perhaps because I am a mathematician and vaguely remember from school that amount of money in the Universe is finite

The amount of money that could exist in the world is finite only in the sense that we could run out of all printable material IE cotton, paper etc and we could run out of parts to create hard-drives to store "digital money" in IE banks, savings accounts, stock accounts etc.
