Beijing prosecutors have revealed a case involving illegal foreign exchange trading using virtual currency. From January to August 2023, Lin and four others used multiple Tether (USDT) accounts and several bank cards to receive large sums of RMB from clients connected to an illegal currency exchange organization. They converted the RMB into USDT and transferred it across borders, effectively engaging in disguised forex trading. The total amount involved exceeded 1.182 billion RMB. In March 2025, the Haidian District Court sentenced the five defendants to two to four years in prison for illegal business operations and imposed fines.
