Banks now are against Bitcoin and the government too. Government and Banks are together a union which wants fee and tax from their users and it is centralized but bitcoin is not like that it is decentralized. Government and banks regulations won't work with bitcoin. So obviously banks hate decentralized currency where they have less role to play if accepted. So no banks won't accept bitcoin in the future too. But bitcoin will be adopted more and more by users like us
I agree with your point of view. I know that bank and governments hate, that people start using bitcoin, because of fees and taxes, which they are too low when you use bitcoin, also you are untrackable if you send or recieve bitcoin, so no one can track you. So when we talk about the future, I don't think that banks will accept bitcoin like an optional currency in the country. They don't like to lose their places.
