I believe that in the future cryptocurrency and banks will unite. but it will be beneficial for banks and countries in which the cryptocurrency will be legalized. cryptocurrency will lose its anonymity and all transfers will again be controlled by the state
I think the bank and crypto will never be able to mix smoothly. The nature of both is contradictory, so it is very difficult for that to happen. If crypto and banking can be merged in the future, then things will be the same as you say, the anonymity of crypto will disappear
