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.
Maybe the banks are prepared to integrate their system to the cryptocurrency, and if it's final, they will release the good news to the public so the crypto can reach more people. I am sure that there will be many ATM installed in many places so we don't have to get a problem when we want to convert the bitcoin to local fiat, and we can directly buy something with bitcoin.
