Frankly, I don't trust banks or their friendship with Bitcoin. Can the two traditional enemies become close friends? I doubt it, because banks are fully centralized, while Bitcoin is fully decentralized.
I believe that such facilitations for banks to deal with Bitcoin and cryptocurrencies may be part of a long-term policy pursued by governments to contain Bitcoin rather than ban it. I hope I'm wrong and that this shift is actually toward adopting Bitcoin and cryptocurrencies, not containing them and centralizing them by linking them to banks.
