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 am a bit 50/50 on this matter. Some banks are still against bitcoins but some are already accepting bitcoins on a trade for fiat money. I think it will be a smart move for banks to accept bitcoins. They could tax the exchange and earn from it thus promoting more and more banks to do the same.
I will support you on this statement of yours dude! in fact, here in my country the is only one bank I knew which is really open for crypto currency and that is Unionbank, I don't if some of you are familiar or heard of it. This banks in my assessment they adapted the scheme of crypto currency, I think they see there is a big potentials in crypto and they maybe saw it also that bring it down which is crypto is not possible for the bank to defeat whether it is bitcoin or crypto.
