Banks are already shooting themselves in the foot. Threatening and closing people's accounts that are suspect of not being "good" citizens.

There is no, talking politely to your valued customer, it is a cease, or we will close your account. This is not he way to keep customers.

And, cryptos are just in the infancy. Imho cryptos will replace the entire financial industry including insurance. Because they are that much better than what exists. And getting better.
