Bitcoin is a currency whether you accept it or not and it was never supposed to become the "world currency" it is supposed to be a global currency which it is.
Governments regulate the economy by issuing money,
Wrong. Governments regular the economy by setting rules and enforcing them not by printing money.
Bitcoin, on the other hand, cannot be controlled, which is why we like it, but also why governments don't like it.
It depends on the country and the government. This is not a global issue.
