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.
I will support your opinion! Banks aren't need to compete with cryptocurrency because it is an institution that monetize the currency. Cryptocurrency will help us to store, pay and transact using P2P services. But banks are responsible for balancing the wealth of economy. Hence, we need bank.
