Firstly, Moderated thread is turning me off, With a second thought, What is a decentralized currency good for if you are handing the whole system to regulations? Normal people need to use decentralized currencies to their advantage, If a sanctioned country wants to evade sanctions, They have many ways to do it and we all have our ideas how they could do it.
Decentralized crypto is a popular concept because no country could manipulate the system, Regulation is manipulating the system on the second page, You could have any amount of any coin, But when you are gonna trade them for something else, You will get locked out.
