I read a quote saying Bitcoin will do to banking industry what emails did to the postal industry.
In the past banks have playes significant role in financing in loans to the public. As gold and silver have been replaced with fiat currency,the banks have reached an almost omnipotent position.
More likely that governments will co-opt crypto and begin issuing their fiat money as a crypto.
I have the same point of view that it is doubted that Bitcoin will be replaced banks. As the huge amount of investors are joining Bitcoin daily. Then a time will comes when Bitcoin will legalize internationally. And as its quality that there is no third party involve in Bitcoin. So there would be no needs of banks in future. Everyone wants his transaction speedy and free of cost.
