[Guangzhou Court Declares Overseas Virtual Currency 'Mining Machine' Sales Contract Invalid] According to Guangzhou Daily, the Guangzhou Intermediate People's Court ruled a sales contract involving a Chinese citizen operating overseas virtual currency 'mining machines' as invalid. In the case, both parties agreed to transport the 'mining machines' to Mongolia for Bitcoin mining. However, the court determined that this activity involves financial security and ecological concerns, constitutes illegal financial activities, disrupts China's financial order, and is subject to Chinese law, thereby declaring the contract invalid. The judgment emphasized that Chinese citizens involved in overseas virtual currency transactions are still bound by Chinese law.
