Bank account where? Our local bank accounts do not accept any kind of crypto exchanges etc.
I need a bank account with card or prepaid card international that wont bother if you exchange bitcoin to them.
in any case, today no bank is ready to provide such services, because users still use additional resources to exchange or buy Bitcoin. Although if we assume that a bank card can make bitcoin financial transactions with an ATM, then this should mean that Bitcoin can be stored in bank accounts too.
