So I doubt if they will even consider a reverse decision to benefit from an increased Bitcoin price. The Chinese government will do anything to control their citizens and Bitcoin was a threat to their power. ("people's democratic dictatorship")

china is not actually as controlling as you think
propaganda makes it a belief that all citizens can only transact using a government approved app. where everyone is using a single app to live from. this is highly untrue. and if you want proof without leaving your town. go to a local currency exchange in your town and just buy some chinese currency. you soon learn you dont need to declare your life history or have a chinese government app to get chinese currency.
take other propaganda
china as a % have less people in detention camps than america. yep as a % of population china is more relaxed of detaining people. (china 0.07%: america 0.12%)
take world trade. everyone knows china does a heck of alot of trade. more then most countries. china do not santion rival countries. yep china make more products and allow more products to cross borders than other countries. the US for instance has more sanctions and product bans with other countries. where USA want to limit its own citizens from trading cross border. heck america even banned a highly branded chocolate egg, citing a choking hazard. yet the UK have been giving these kids these chocolate eggs without a problem
im not a chinese resident (im british white) but the propaganda of trying to make china look like evil dictators is a media problem not a political problem
