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?
Bitcoin is very huge and very potentiating crypto currency and this is the reason why millions of people around the world are investing into bitcoin and there is no doubt that one day it will surely get legalised and centralised all over the world, the only defect with bitcoin is its illegal use and once it will get centralised globally there will be no illegal use as then there will be the governments of each nation who could keep eye over all the bitcoin activities and banks will also accepts the bitcoin very easily.
