It is the inevitable future! Banks will eventually have to move to the digital currencies whether they like it or not! However, please note the point that, these digital currencies will simple be a digital representation of the paper money and nothing else! So there's nothing to get excited about! Mark my word, that Banks will never support a semi-anonymous digital currency or decentralization, no country would approve this move. It's simply a number in your bank account instead of holding cold hard cash! Centralized and strictly  controlled by the governments!
