What I know is that, every innovations modifies the old structural development of an institutions as the purpose to everything is civilization, the case of crypto investment and banks is quite a new innovations just like postal office and emails bringing in new system of message delivery too. So it's nice embracing new innovations when it comes and be part of it.

Crypto serves multiple purposes, cross border transactions and investments (long and short term), Banks doesn't offer much other than savings with no increase in values, investing with low percentage rate for longer period but has limited amount which only favours the rich which is discrimination.
