china is one of the powerful country in this world.they are in a high position in economy.and also china is well developed country.but they still don't like bitcoin revolution.what is the main reason for that?
This is simply because they want control and they can never do that to bitcoin. The decentralization and volatility of bitcoin is simply creating allergies to their way of governance. The government can't tax it so intonsis they can't earn from it. So they become allergic by it's very nature. In time if they can fine a hole where they can atleast fine a way to profit from it by then surely will have a cure for the allergy.
