And bitcoin has faster transactions than the bank and more secure I guess.
Neh, you're wrong. IMO, bitcoins aren't that secured as compared to bank. Bitcoins, if ever hacked, you loose 'em forever but it isn't the case with the banks.
What are you talking about? Bitcoin is definitely more secure than a bank. If a bank gets robbed, there goes all your money. If a bank gets hacked, there goes all your money. With Bitcoin, you can get a paper wallet and be completely safe.
