I agree with some people out there..
I believe that one day bank will gonna disappear because in years ago people do not have Bank to transfer their money or save their money. And once people fully accept bitcoin and by the government the start of bank disappering will happen. Support is only bitcoin needs from the government.
It's far from happening. Support from government is like asking your boss to make you hold his money when he has no idea who you are. Banks are holding many transaction, from local to sometimes up to abroad. They do not just deal with money.
I do agree that soon banks will be more into going digital in transactions to make their transactions faster, with that said, I am sure banks will evolve too.
