Bitcoin has been announced since the day it was invented, and it will be suppressed by governments in the future and declared illegal currency. Is the basis, the further development of the currency will be in the interests of the threat to traditional monetary and ruler, not the rights to cryptography currency once governments announced that the currency is illegal, its price will produce volatile in the short term, and may even crash. At the same time, the government will force the bitcoin exchange to be shut down, so that bitcoin can only be sold in private, and its exchange capacity will be badly hit. Will the government ban bitcoin?
The government has really the power to banned bitcoin because there are already a lot of countries who already banned bitcoin. I think the reason why the government banned bitcoin because there are some people who used bitcoin for there illegal activities that is why the government sees bitcoin as a illegal currency.
