That might be true, but the risks to individuals in mainland China is extremely huge if one is considered to be an enemy of the people, state and party. That is not going to be a fun ride to puy it mildly.
In any case this takes away a lot of the potential crypto could have had in the future and will probably cause a reaction in the next weeks, months and maybe years to come.
This is why I couldn't blame other Chinese citizens to stay away from mainland China and seek shelter or freedom in Special Administrative Region (SAR) like Hong Kong or Macau. Those said regions are more likely to experience freedom and free speech and doesn't need to be scared of their mainland's Socialism.
Nevertheless, I think the cryptocurrencies are still widely used by the citizens in SAR especially in Macau that gambling is allowed like and they are known to be the Las Vegas of the East.
