A digital run is imminent. Banks will have to take it seriously otherwise, they will be simply left behind in the competition. Just an hypothetical example, There was a small cooperative bank in my area which doesn't have any internet banking facility. They were running on ancient bookkeeping method. They were getting a good amount of business from the local people because the locals didn't have any other choice. Now suddenly, the biggest private bank of my country opened a branch in my area with all modern facilities like internet banking, ATM machines and Home banking. Within 3 years, that cooperative bank disappeared from the map because they couldn't evolve with the changing need of the consumers.

I am sure, the banking industry is now facing the same challenge with crypto currency market. The kind of freedom and facility is offered by a crypto currency, banks are not able think off because they are a regulated entity. So soon they will have only two choices in hand, either they adopt crypto currency or they simple vanish from the map. However, this transition will happen quickly. It may take 10-15 years from now, but will happen surely!
