Well china and their "One country, two systems" has always been very confusing. Especially now when there shouldn't be 2 systems but china is apparently too afraid to bring full commnunism to hong kong. Or they have a time frame for that. It would probably cause mayhem of biblical scale to try to implement it right away.
Yeah righ it little bit confusing mainland china ban related to bitcoin trading and mining but they still produce the miner
but in the other hand they might tell hongkong to implement crypto are they gonna work or not if they work maybe the might lifting the ban and start the crypto in the mainland china aswelltho they also created Central Bank Digital currency today
