"Banks are old and slow, technology is fast and new" so technology will win. That is totally reasonable logic. But bitcoin provides no protection from fraud by design. If someone breaks into your house or hacks your computer and steals your private key you have no way of getting that bitcoin back. But if someone impersonates you at the bank the bank has ways of refunding you. Maybe some people prefer the bitcoin design, but most people will not.
