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?
We cannot predict it now. Anything can happen...good things are expected but unfortunately if something bad happens then we humans have got enough potential to fix it.
