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 think banks now is just on the adjustment period where they initially consider cryptocurrency investment as a potential threat to their business for the reason that they will fight for investors but I shared I think banks will do on the long term is that they can really incorporate or adapt the idea of cryptocurrency. They will soon realized that they do not need to battle with cryptocurrencies but instead to cooperate with it. They already see the growing number of digital coin investors and these banks can capture these type of investors only by also offering cryptocurrencies.
