I think it is great that China is the world’s largest producer of Bitcoin mining. This shows how powerful and influential China is in the cryptocurrency industry. With the amount of Bitcoin produced in China, it is clear that the country is a major player in the cryptocurrency market and is likely to remain so in the future.
Before creating a post, make sure you're already read the other replies too, have made few research and not only agree with any words written by @OP. As you can see the quoted part below, China already ban Bitcoin mining since 2021, there's no more mining activity you can find in China because it's illegal.
Bitmain headquarter company was in China, but it seems they're already move to United States because they're failed to launch IPO in China.
China sent shockwaves through the blockchain sector in 2021, when it announced extreme restrictions on Bitcoin (BTC) mining and crypto trading. It imposed the ban in phases, and by late-September 2021, the government put a stop to all crypto transactions. Within months, Bitcoin's hash rate plummeted, and Chinese crypto exchanges left the country, leaving many BTC supporters unsure of how the industry would recover after Beijing's ruling.
