I do not see the reason why banks would and should be against cryptocurrency.With the technological advancement, i see they rather integrating the cryptosystem into their work . There should be more crypto ATMs and banks too.
because cryptocurrency threatens the existence of banks, let alone a decentralized system differs 360 degrees from the bank system? of course that is what makes banks against crypto, because it is very possible that people will prefer decentralization more freely than the bank system
