there is a possibility that banks will receive crypto exchange, but it is very difficult because there is a need for regulation to ensure that security is maintained. because all this time the bank always needs identity and personal data, it is in contrast to cryptocurrency system that does not require identity and personal data.
In my views, I think that time will come that banks will transact and exchange cryptocurrencies because this has become more popular nowadays. Perhaps, this has been into consideration in the future of bank transactions which will be more adaptable to the cryptocurrency users.
in my opinion, crypto is more famous than now, many people use crypto for payment in online and offline store
then all country in the world start to accept crypto, goverment know that crypto not crime, not money laundring because crypto is bring big usefull for user
