On October 15th, according to the WeChat official account of the "Hunan Internet Police", recently, the Fuzhou police found a case clue that provided fund transfer and payment settlement for underground industry platforms such as online fraud in their work. The amount involved was huge, and the police quickly set up a task force to investigate the case. After research and judgment, the police successfully figured out the criminal context and found out that the criminal gang used virtual currency stablecoins to provide funds transfer payment for the black and gray industry of illegal futures platforms through the operation of a fourth-party payment platform, and earned rebates from it.
