Which means if they want to get in and they do want to get in than they need to find other stuff to invest into. The first thing that comes to my mind is crypto related companies, so big financial companies will be investing into companies like coinbase which they are already doing but will start to look at smaller stuff as well, with smaller companies getting millions of dollars the crypto company space will get much bigger and the valuations of those companies will be a lot.
I think a lot of big money that wants to move into crypto can benefit from using some form of crypto bank imo.
