China has long banned its citizens from mining bitcoins because they are unable to regulate the circulation of bitcoins, the regulations applied by China will never have problems with crypto in the future, other countries will never follow China and many countries also support bitcoin as a tool investment
Each country has different regulations in dealing with this or in dealing with cryptocurrency issues, because as long as it doesn't harm the country, I don't think there will be an instant ban on everyone, because those who use cryptocurrencies also don't make public announcements.
