I think why government is doesn't like cryptocurrency because they think if cryptocurrency will make them real currency will get a loss.
I don't really know the truth but i just think like that.
They all so worry about a real currency like USD, IDR, EURO and other real currency.
Cryptocurrencies are competitors to the fiat currencies created by governments, before bitcoin appeared there were plans to create a one world currency, such a currency will be used to take complete control of the lives of the people because if they did not cooperate then they will not be able to buy anything without that money, but now thanks to Satoshi the vision of a world that is dominated by a single currency is completely gone.
