If you can't beat them - join them. When cryptocurrencies reach a certain critical mass banks will swiftly reengineer themselves.
And also, just maybe, those will be new banks, created specifically for crypto

You are right. I am wondering what the new banks for crypto can benefit the users. If the crypto banks exist means it should have some fees and the account holder can no longer be anonymous (which can be good in terms of dealing with money laundering). So the users will not be happy about this.

yeah. or basically just mandate all exchanges to comply with AML/KYC, and make that the only legal way to convert between crypto and fiat. Let crypto be unregulated, but perform checks when someone wants to cash out.

I don't want banks to support it. I would love for banks to crumble as we all move on to a currency that we can control.

This day is very far away~
Because the economic nowadays are all base on the monetary policy, but I think in no longer future, both currency​ and crypto currency would play an important role in different countries.
