[U.S. Prosecutors File Lawsuit to Recover 3,444,000 Fraudulent USDT] The U.S. Attorney's Office for the District of Massachusetts has filed a civil forfeiture lawsuit seeking to recover approximately 3,444,000 USDT (valued at approximately $3,444,000), which are alleged proceeds of an online investment fraud and money laundering scheme. The case involves four victims, including two residents of Massachusetts, one resident of Utah, and one resident of South Carolina. The fraudsters lured victims into investing in a so-called Ethereum project backed by physical gold through text messages or encrypted communication apps. After purchasing ETH, the victims transferred the funds to wallets controlled by the fraudsters, where the funds were converted into USDT and transferred to non-custodial wallets.
