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.
The reason behind the bank's are always against in crypto currency because for them crypto currency is the biggest compitence to their investment. Because they lose big amount of profits if their customer's transfer to invest their money in crypto currencies. The bank gives a small amount of interest to their customer's in a long term deposits which is not good to the part of their customer's.
