China may be trying to ban BTC but there he been news they are not actually. The language barrier is deceiving us all and the media is also making us confuse us with what they are doing. But we can see their Hong Kong is adopting BTC. And some news BTC is still mined in China.
So if BTC is being adopted in US through Trump to put the US economy at its advantage, it wouldn't be surprising if China and Russia will do the same.
The question for them would be would they be able to take the lead, or would they remain in the US shadows for this one.
In my opinion - it will be the case because for now, the sentiment and the situation seem to be going the way we speculate it to.
