At current situation it can not make any bank disappear but after many years it may not be predicted. It may also make banks disappear by using digital money not physical one....
It would never happen.!!! The central bank is, as of any Government. Without a bank then every country will be screwed to take care of any existing financial in it, so until whenever the bank will remain standing and bitcoin may never replace him. Because I think the Bank is permanent in every country, it is better meikirkan how to get a lot of advantages in the bitcoin instead of having to think of something that only generates a prediction
Never say never , even though it sounds like impossible
Things can changed faster as time goes by especially when you are talking about technology like bitcoin
I put my faith in bitcoin also a little bit doubt about this kind thought
The way bank works could changed when people realized how benefical bitcoin it is.
