In US, BTC had a use such as on Silkroad for drugs and other stuff; in China, at least from what I understand, it has a use of transferring assets out of the country.

If you talk about China specifically, the average people wouldn't consider governments 'oppressive', the approval rate for government is actually quite high.

Lol like average people there are invested in Crypto?

I'd say it's because it's kind of the "wild west" and they can do scammy stuff and not get hit by the government like in the US or europe.

Are you sure it’s not because that’s where scams and cyber attacks against the west come from?

Yessir, it's surely because of that and not because of the complete state collapse a lot of these people witnessed first hand.

Are you sure it's not because that's where cyber attacks come from? Because you do know that trading cryptos is illegal in China. Do you have any data to back up your assertion?
