I think Bitcoin will not make the banks disappear but also make it even more development. Because, the value of Bitcoin will also be converted into money, where money exists, it is certain that banks will also survive. I believe the banks will change rather than disappear. They will change to be able to work with Bitcoin. In addition, banks are inevitable needs of each person when they want to borrow money, save money, change money, transfer money, ... nothing can change it. Therefore, the bank will not disappear
