Bitcoin (BTC) is an encrypted digital currency based on open source P2P software, Hash algorithm and blockchain technology, which is constantly attracting domestic and foreign investors to compete for "mining" because of its decentralized, non-additional and infinitely segmented characteristics. As a result, bitcoin has continued to rise since its appearance on the Internet trading platform in 2009, but its drawbacks of not being controlled by the government have caused it to experience a cycle of spurt growth and diving decline. Although China implements "one-size-fits-all" management measures in Bitcoin regulation and uses the word "must not" in relevant documents, the trading volume of Bitcoin in China remains high, and it has spawned criminal supervision, financial system, and social market risks, constantly challenging the nerves of government regulators. On the basis of analyzing the characteristics and risks of Bitcoin, this paper discusses the two documents issued in 2013 and the Announcement on Preventing the Risk of Token Issuance and Financing issued in 2017, clarifying China's regulatory attitude towards Bitcoin, with a view to providing new ideas for national governance of Bitcoin.
