If you take banknotes and coins from the U.S. dollar, it is basically a cryptocurrency, completely mined and controlled by the US government. This is why the United States and other governments are afraid of BTC. In any case, in 10 years, the currency will basically be digital. As a society, we rarely use cash anymore. This is why BTC is better. It is mined by anyone, no one controls, no leader or speaking mind. This is why it is superior, and countries will do everything they can to stop it. I don't think they can. They have waited for a long time, and now the organization is involved. If they take it out after the crash in 2017, they may win.
