Just as the digital era, the photographic industry witnessed the bankruptcy of Kodak, the rise of online music, the disc has also been quickly eliminated, after the advent of bitcoin, the financial industry may also need to carry out major rectification. Will the bank disappear?
you are right that the bank will actually disappear when bitcoin is in effect worldwide, if the bank does not fix itself then they will lose their role if this is not they want then the bank should add their function, for example, to be exchager or others.
There has to be something interesting that the Bank will not miss its customers, it's like an attractive promo as well as many other sophisticated features. If viewed from the sophistication of the blockchain technology used by Bitcoin is an extraordinary thing. If this is maintained and no changes made by the bank then the Bank may disappear.
