Thailand's DSI says a Chinese 'grey capital' network used 6,390 mining rigs and cash mules to launder over $300M a year. No arrests yet; the probe continues.
Thailand's Department of Special Investigation seized 6,390 cryptocurrency mining rigs as part of a probe into a Chinese-linked network that the agency says laundered over $300 million a year through illegal mining and cash mules.
The DSI described the network as a "grey capital" group that exploited regulatory gaps in Thailand's crypto oversight. Mining rigs generated digital assets that could be sold on exchanges with limited scrutiny, effectively creating a cover for moving money across borders. Cash mules physically carried funds outside the banking system, the department said.
The seizure ranks among the largest in Southeast Asia. Mining operations consume large amounts of electricity and produce coins that can be traded anonymously, making them attractive for disguising the origin of illicit funds, the DSI said. The network moved money through multiple channels, complicating enforcement.
Thailand has tightened rules on crypto exchanges, requiring customer identity verification last year. The DSI investigation extends enforcement to the mining infrastructure itself. The department said it is coordinating with international law enforcement to trace the broader network.
The DSI's use of the term "grey capital" points to a network that operated in a legal grey area, using mining hardware and cash couriers to bypass traditional banking oversight. The $300 million annual flow, if the DSI's figures hold, represents a significant channel for moving illicit funds out of China through Southeast Asia.
No arrests have been announced. The DSI has not disclosed potential charges or a timeline. The investigation continues.
