Official WeChat account of the First Intermediate People's Court of Hainan Province announced the trial result of a "mining" contract dispute case. It pointed out that the relevant agreements signed by purchasing dedicated "mining machines" to calculate and produce virtual currency through "mining" activities do not comply with the spirit of Article 9 of the Civil Code of the People's Republic of China or mandatory provisions of relevant administrative regulations. They are detrimental to social public interests and violate public order and good customs, and therefore should be invalid. The risk of losses from providing services such as purchasing "mining machines" and leasing venues for hosting is borne by the provider. "Mining" is a risk investment activity, and the policy risks, technical risks, and investment loss risks caused by it during the "mining" process should be borne by the investor.
