If you took away the paper cash and coin from the US dollar, it’s basically a crypto currency, solely mined and controlled by the US government. This is why the US and other governments are afraid of BTC. Money is basically going to be all digital in 10 years at this point anyway. As a society, we rarely use cash anymore. This is why BTC is better. It’s mined by anyone and controlled by no one, no leader or talking head. That ls why it’s superior and countries will do anything they can to stop it. I don’t think they can, they waited to long and institutions have skin in the game now. They could have probably won if they took it out after the 2017 crash.
