Governments want to control cryptocurrencies and they do not understand how they can control the bitcoins and crypto even if they regulate it.
Also, there is a lack of knowledge and understanding when it comes to bitcoin and governments are afraid to regulate it.
They are the heads and managers of a country, I think they know it all, they don't say they don't know. Many governments have yet to take any action on crypto simply because they are observing, need more time to evaluate it and then they will act once they have made a decision. Believe me, no government ignores cryptocurrency, it is a huge source of tax revenue for them.
