As of now, I think there are banks who are already adapting blockchain technology and also bitcoins. Even some countries are recognizing bitcoin as a currency in coins. Slowly, the government will pass laws to regulate and control this bitcoin.
I may live in Serbia, but I didn't heard about banks making plans with bitcoin, I've heard for a few countries speaking about bitcoin (not including those who banned it). I seriously hopw that our government talk a little about bitcoin and maybe offer some bills to be payed in bitcoin, but that's so far from today for Serbia.
