Once dealt with the real banks and their system, you will not want to trust anyone else. What will be different "bitcoin bank" from those that now is not clear. Perhaps the word "bank" is alarming, but still, the financiers are special people. Still, what currency they celebrate.
I don't know for sure what the intent of the bitcoin Bank. Because of that I know of that bitcoin is bank. But banks in the context of what I mean is a private bank, so we are the owner of any bank of any wallet btc that we have. Why should be discussing something that did not yet we can think properly, the better we do something things can indeed help our lives and also help someone who is need it
