No, I do not believe that. We must admit that what has allowed banks to acquire so much economic power is their ability to understand where capital is, and make the necessary efforts to keep it.
Knowing that banks will never fight against capital, what I see today is a growing interest of banks to incorporate blockchain technologies into their processes, and because of their marked interest in taking over everyone's money, it would not be strange that in the near future we will see banks willing to accept cryptocurrencies to carry out financial transactions.
Yes bank for against cryptocurrencies because banks don't want to take any type of risk. but in future if Bitcoin is becoming the mainstream then we need Crypto banks also and they will not be against cryptocurrencies so don't worry about that infact these banks will upgrade to prepare banks only.
