Actually Bitcoin does not need anyone’s approval to run or be used. Anyone can use it since it is decentralized irrespective of the fact that whether any country approves it or not. The approval here means that a country is making it legal to be used by the people of that particular country.but in the end still bitcoin needs the approval of the government for it to last since we all need the favor of our government, at the end of the day if it has an effect already in the economy the government has the right to decide.
