Who is mining in China if miners are facing prosecution? Most mining used to take place in China in 2013-17 but i doubt it still is. Some Chinese miners were moving to Canada earlier this year, while some went to Russia.
What most articles don't tell you is that the miners aren't just one entity, but a group of hundreds or thousands of smaller miners from all over the world. So while the pool itself might be Chinese, the majority of its network allocation doesn't necessarily have to be.
Plenty of mining happens in Scandinavian countries, in various parts of the US, Canada, Russia, South America, Europe, etc. If Pools get hit with sanctions, you'll see the miners within the pool simply connect to another one. It's more decentralized than it actually looks, but news outlets aren't in the mood to explain that to their rookie followers.
The annoying aspect of reading translated Chinese articles is that we can't fact check the source unless we have a native Chinese buddy to ask for assistance.
