Some dude who spends $450K/year wants to hire someone (who likely wouldn’t even make $450K/year) to help him figure out where he spends all that money. He can’t even be bothered to monitor his own accounts on a monthly basis to make a basic budget. Do you think that guy is ever going to take responsibility for holding his own private keys?
There are multimillionaires asking financial advisors who don’t even have a fraction of their wealth for permission to retire early. Do you think they will hold their own keys?
There will be bitcoin banks. Let’s make sure they are full reserve banks.
