I would not trust that. I don't believe that any country that rejects the free market can become a mecca, or can satisfactorily allow the development of cryptos in its territory, not Iran, not Russia, not Venezuela. I would only trust China, and that is because they are quite capable, although everything depends on their interests.
If they don't support the free market at this point, it is because they don't take smart economic actions, I don't think that this will change as technology evolves, it is a matter of the rulers.
Good points.
I think it just makes the case for BTC stronger, as it's controlled by no government.
