Bitcoin only had a $9B market cap at it's peak. That wasn't even enough wealth to attract Wall Street. Bitcoin holders are a long way from "truly wealthy" by their standards.
That is somewhat comforting and disconcerting at the same time...
I suppose the "truly wealthy" will still have their estates and security guards and such and if things get bad the poor suckers holding bitcoins will just be targets.
(Edit- good thing bitcoin it's gonna crash to zero. And just in case it doesn't, I'm gonna buy extras for all my friends... You know, just in case...)
