Not just for China alone but for all countries who have been eyeing bitcoin since El Salvador adopted it as a legal tender. The plan to legalize crypto is supported by the Central bank of Russia so they are now lifting the ban on crypto mining and trading. Russia was more encouraged too because they have seen India on legalizing the tax for digital assets, and from here, we can expect for a wider adoption for crypto in the next couple of months.
Personally I find it difficult to implement if all countries legalize Btc as a legal tender and only allow it to be traded like a commodity. Crypto is currently regulated by Whales, if the state legalizes BTC as a legal tender then its stability is in the hands of Whales, I also don't really agree to fully use BTC.
It is the matter of time when the whales have the control or it may also be not like that which you think. But it is sure that if all the countries will accept bitcoin as their legal currency to be used in the country then a day will come when it will be fully decentralized and not a single person or a small group will control it.
