This is a new one for me. So we have no single Bitcoin mining activity in China?
I am sure that some people are mining in secrecy even if it has been banned, but the majority of Chinese miners have migrated to other countries. Many went to the United States, others moved to Kazakhstan, Russia, and other locations closer to China. When the ban was announced, the BTC hash rate dropped by 40-50% because Chinese mining companies were closing up shop.
China Bitcoin mining hash rate fell from more than 60% in May and close to zero in August, this shows that mining activities in China have stopped completely and the mining ban by the Chinese government has succeeded in making many miners move to Kazakhstan, even Kazakhstan reportedly is now the second largest country for crypto miners in the world, in my opinion a ban from china of course will not be able to kill the development of bitcoin, because if one country prohibits mining of course miners will continue to move to other countries, and even in my opinion right now bitcoin mining starts to grow rapidly in various countries like mushrooms that grow in the rainy season.
