practically all of us here can see that the government they always want to control and manipulate the assets of all the people, they are angry at virtual currency because it makes everyone independent they and they cannot make a profit from each of us citizens, so the contradiction between the banking government and the virtual currency BTC is really difficult to develop together. Because the true nature of BTC has taken away their huge source of income. then there's no reason they should fully accept BTC.
some governments accept bitcoin completely, but others refuse to accept bitcoin because it would be a threat. we know bitcoin can not be controlled by anyone but bitcoin can still be manipulated by groups of whales. Banks and bitcoin have their respective advantages and disadvantages, so they will not be able to unite, they can develop payment technology side by side.
