The news about China's Bitcoin mining ban has been frequently mentioned many times over the years and the truth is that only miners know it. The Chinese government has quietly let miners mine Bitcoin for years, and they know how beneficial that can be. Bitcoin mining equipment is largely made in China.

The problem of the computing power of the Bitcoin network may decrease but then it will continue to increase because Bitcoin mining is very profitable. Part of the new devices coming out has more efficient mining technology so I believe the hash rate will always grow.
