banks accepting bitcoin is not such a great news though! it can even be a terrible news if you ask me. because if banks start accepting bitcoin, open bitcoin "accounts" and things like that, it may encourage people to start using banks instead of avoiding them and having their own bitcoin wallet. and that is terrible because they would be going back to the centralization that were trying to get rid of.
In my opinion, the use of Bitcoin and other cryptocurrency by banks will mainly consist in services for exchanging cryptocurrency for fiat and vice versa. And then, this will happen only when the states legalize cryptocurrency and banks receive detailed instructions on the use of cryptocurrency.
I see no reason why banks open a cryptocurrency account. It will be very risky to give out loans in banks for cryptocurrency. In any case, I think that state banks will not do this. Commercial banks may risk, but this service is unlikely to be widespread.
