At present only a few countries that accept crypto currency while other countries prefer to banded bitcoin. Bitcoin can be legal so in this world seems to be very difficult because there are still many countries that consider cypto could disrupt the stability of the economy.
The government is very careful in making decisions about bitcoin, because the government is worried about losing control over the circulation of money if bitcoin is legal, unlike fiat money which is under government control in this case the central bank as a policy maker. Fiat money is centralized while bitcoin is decentralized, clearly operating outside government authority because transactions are peer to peer, as if we have our own bank.
This needs be think of a lot of times, we always think that bitcoin is a very big help in our economy however government has its own purpose why, this is just to protect our contry and to lessen the crimes, fraud and any other illigal activites that may happen because of crypto.
