China has indeed carried out a mining system that is so large, in that country the mining industry has become a common thing and even large companies spend one warehouse full of mining tools. In energy treatment, in China the electricity needs are so large, there are so many mining tools that are used and that is what causes the spread of Bitcoin so very large in China and is very different compared to other countries.
In my opinion there needs to be a regulation that regulates the circulation and use of mining equipment in China, it is far wiser than having to ban mining activities completely.
