I see this thing a little bit different. Banks will realize the big potential of crypto currencies and they can invest a lot of money. You will be able to upload any crypto directly on a credit or debit card and just pay your bill like now. People will not even know the difference. Bank will exchange it to any fiat in any country. We'll gonna pay fees and exchange like now, and banks will take advantage of fast and simple transactions. We can only benefit if we grab as much crypto while is still cheap. But, hey. What do I know, I'm just a guy on a steemit.
