According to Odaily Planet Daily, in the first half of 2025, the Hanjiang District People's Court of Putian City, Fujian Province, heard and sentenced a virtual currency-related criminal case. Yan, Zheng, Lin, and others used USDT to establish an underground foreign exchange network, recruiting clients through overseas chat software and illegally exchanging RMB for foreign currencies using "U-coins." The bank transactions involved exceeded 13.3 billion yuan, with the illegal transaction amount reaching 25.62 million yuan.

The gang withdrew over 478 million yuan in cash from banks in various locations, purchased "U-coins," and transferred them to the wallets of upstream criminals, using them to launder cross-border funds and profit from the proceeds. During the trial, prosecutors extracted voice information from a co-defendant's phone and verified it matched Lin's voiceprint, establishing a connection between him and the accounts involved. Ultimately, the court found their actions guilty of illegal business operations and aiding in cybercrime. Fifteen individuals, including Yan, Zheng, and Lin, received prison sentences ranging from eight months to three years and fines. (Putian Net)
