Why do we need "Bitcoin bank" where in fact we already have bank in the forms of web based wallets that are reliable and secure for a long time? Well, not unless if all those wallets will have bad issues that would destroy their reputations to its users would then be the best reason to shift to that "Bitcoin bank" with no ounce of hesitation.
What is the use of bitcoin wallets if there are bitcoin banks? I mean, you can just save your bitcoins in your bitcoin wallet and not in these "bitcoin banks"? Better use a bitcoin wallet where no one is controling and holding my bitcoin but myself. Also I can manage it in my own, well if the user has their porblem in holding and using his or her bitcoins they can hire someone or a third party to help them.
