Bitcoin is different than bank and vice versa, I think Bitcoin and bank will do their specific task, I think Bank will not against crypto's because crypto not disturb bank, and I think crypto will give good impact to the bank, because when we want ro withdraw the money we need bank account and that make will be more peoples will use bank services (this like at my country) and the bank will have more customers and that make get the profit from our fee when do a transaction.
