The main thing here is that banks won't go away despite a lot of people here thinking they will. Banks can easily adapt to the changed money climate, and they are faster than we are in doing so. In the end, it doesn't really matter what form of money we're using, they just want to make sure they can be part of it and charge fees in the process.
I see a time where banks will be the main entry points to crypto for people. It's convenient, you don't have to wire money to foreign bank, and KYC/AML isn't necessary because your bank has all your information already. I'm sure they'll throw in insurance as well as extra service.
I really like Bank of America now. It's pretty obvious that is the right direction in terms of future possible results and the fastest way of pushing humanity forward in the progress perspective.
And i agree with you, it will be the main entry point for the masses. Some that think like us will take care of their own things most likely but i believe that even some if not a lot of us will consider banks seriously if they offer an attractive interest rate.
