I dont see any major changes in banking sector nowadays. From banks, I only get notifications that my account monthly fee will be higher, and changes of plastic card limits. I understand that every bank in every country is different, but except an option to buy car insurance, I cant remember nothing innovative during last 5 years. As to Bitcoin, what new can it innovate? We are only waiting for mass adoption and that is it.
Why do people rob banks? As bank robber Willie Sutton said, "Because the money is there."
Bitcoin itself is a technological innovation. Bitcoin is the first application of the underlying technology of the blockchain. It is not too much to say that robbers need to understand hacking techniques in the future.
