The main thing is about CONTROL. Governments like to control things and while that’s a freaky thought, that’s their job. Any form and type of government should control and maintain records for security purposes. Who knows if the money goes to illegal activities like funding terrorism? It’s a legitimate threat. But since crypto is decentralized, governments have all the reason in the world to be terrified. If they regulate crypto, then they’d have seemingly more control compared to literally nothing if they don’t.
