As far as my country is concerned there is no bank that accepts bitcoin and I don't see it happening even in future as the government of my country will never allow that to happen.
Bitcoin is a threat to banking system and also to fiat money and government is well aware about it and no government will allow any digital currency to replace their national currency.
Bitcoin is completely against the rules of Governments and banks just because of this its not going to happen until some one big take risk and bring some more regulations for this in developed countries like Japan Sweden and Netherlands because currently they are best countries for this
