My main concern with crypto is that the banks are the real government, and therefore the government controls:
- The fiat to crypto and back transfers
- The payment systems
- The Internet that is used to do the two above.
It's a serious concern. Also, governments have unlimited processing power and "free" electricity. They are certainly mining. Crypto is the opposite of Gresham's Law too. Good crypto will replace bad crypto. Well, we never know when a better crypto will be created.
Worse, the government can simply shut down the fiat to crypto transfers using banks. What would the value of BTC be if that happened? I suspect it would be a lot lower.
