China will also clamp down on illegal activities in the securities market, and maintain the stability of stock, bond and forex markets, the State Council's Financial Stability and Development Committee said after the meeting.
China powers most of the world's bitcoin mining. According to data from the Cambridge Center for Alternative Finance, China accounted for over 70 percent of the world's computing power for bitcoin between September 2019 and April 2020.
Cryptocurrency mining has drawn regulatory attention in China in recent years. In April 2019, China's National Development and Reform Commission put cryptocurrency mining on a preliminary list of industries it wanted to eliminate, citing concerns including energy-wasting and regulation. However, the final version released in November removed cryptocurrency mining from the list.
In June 2019, China's central bank – the People's Bank of China – issued a statement saying it would ban all domestic and foreign cryptocurrency exchanges and Initial Coin Offering websites.
By the end of April 2021, north China's Inner Mongolia Autonomous Region said it would "clean up and shut down" all cryptocurrency mining operations to reduce carbon emissions in the coal-based region.
Beset by the escalating regulations in major economies, bitcoin failed to recover from its tumble week after Tesla's CEO Elon Musk's tweets doubting its environmental impacts. The U.S. Treasury Department on Thursday also called for new rules that would require large cryptocurrency transfers to be reported to the Internal Revenue Service and the Federal Reserve flagged the risks cryptocurrencies posed to financial stability.
China's Hong Kong also proposed on Friday that cryptocurrency exchanges operating in the city will have to be licensed by the markets regulator and will only be allowed to provide services to professional investors.
At time of writing, bitcoin is traded at $37,000 each, about half from its all-time high a month ago of over $63,500 and similar to the level of the beginning of the year.
