I think government has the power to control but not to kill bitcoin at all, in fact we hear some news that government are warning people about investing in bitcoin and some other negative comments about bitcoin. Since it is already widespread all over the world and lot of people are engage with it, and lot of people are relying especially those who are unemployed because they got an earning through bitcoin so we can say that government cannot directly kill or stop bitcoin because of the people.
Yes bitcoin is the independent currency and it is not in the control of the government at all. People are investing and making bitcoin high, so I think it will not be ban according to the will of government at all. They will not kill bitcoin because they know that bitcoin will be the future of country people. So no government would ever try to ban or stop the growth of bitcoin in their country, bitcoin is improving day by day with price and value because investors are investing in bitcoin currency, so it is unstoppable investment right now.
