This topic is too untargeted. I didn’t say which country’s government policies are beneficial to cryptocurrency, otherwise I don’t know where to start.
However, the national government's policies have always had a great impact on the encryption field. For example, a small country in El Salvador uses Bitcoin as a payment currency. Although El Salvador is a small country, its influence on the international stage is still great.
If it is a favorable policy for the cryptocurrency market, it will definitely cause the market trend to rise. Of course, unfavorable news can also cause market panic.
