I will tell the situation in my country that bitcoin had good status because recently my government has just make some policies to protect bitcoin users and i think this is bright move because although bitcoin still hasn't admitted globally and some people are still doubt about it but at least my government have concern to develop of bitcoin
In order for bitcoin to be accepted globally, it has to be accepted by countries. One at a time each. I also think that it starts small. If the people from your country uses bitcoin a lot, it will later on reach the authorities and they would see the effects of bitcoin to their countries.
About the question would bank will accept bitcoin someday and if we see the movement of my government i am quite confident in the next few years the bank will starting to build the facilities to bitcoin users to accept deposit and withdraw for bitcoin
In a few years, bitcoin would be so in demand that banks will have no choice but to accept unless they want to be left behind.
