In future if bitcoin is allowed in countries around the world and most online based companies will start to allow bitcoin as their payment currency/gateway/exchange. But what do you think if we would be allowed to transfer our money to our bitcoin wallet from our bank accounts like PayPal does? Will it be a good thing for banks and us?
I think it is only a question of time. New services pop up every time - for example, today I have heard of this new Revolut card, revolutionizing the way you can pay with cards with different fiat currencies. Who knows, maybe tomorrow it will be a service doing bitcoin in cooperation with banks.
