Beijing still trying to figure out how to control (=ban) the mining activity in the country...
everything will come down to the corruption in China, and in the end they can not even put a dent in Chinese mining operations.
it runs deep and with the added financial situation in China and the fact that mining is filling the pockets of so many people legit or through bribes, it can not be closed at all.
imagine a small city that has a small power plant that is alive only because of the mining farm. the city people are earning money because they have a job in the mining farm or in the power plant or anything related to this mining operation. there are officials that see this and may even be bribed to let the mining go on.
the government goes to this city and tries shutting down the farm. they will shut it down for a couple of hours and they say "we ban bitcoin now. everything fine" then things will be started soon afterwards.
