Thailand's DSI expands its probe into a $300 million money laundering scheme linked to illegal cryptocurrency mining operations.
Thailand Intensifies Investigation into Cryptocurrency Money Laundering
The Department of Special Investigation (DSI) in Thailand is ramping up its investigation into a vast network allegedly linked to "grey Chinese capital" that has been reportedly laundering over 10 billion baht, or approximately $300 million, annually through illegal cryptocurrency mining operations.
Authorities have confiscated more than 6,390 mining rigs and estimated that the power theft involved exceeds 953 million baht ($29 million). In total, eight arrest warrants have been issued for individuals involved, including four Chinese financiers and four from Myanmar.
According to the DSI, these mining operations served as a front for laundering money derived from call-center fraud and online gambling, with couriers withdrawing between 30 to 50 million baht daily from Thai banks. This significant figure indicates a well-organized operation with extensive financial networks.
The investigation follows a series of raids that began in December 2025, when the DSI's Technology and Cyber Crime Bureau dismantled three major mining operations accused of stealing electricity. This marked one of the largest utility thefts in Thailand's recent history, with damages reported to the Provincial Electricity Authority.
Among those implicated in the scheme is Wang Yicheng, a businessman based in Bangkok. He is linked to a digital asset fraud case being investigated by U.S. authorities, with over $17.8 million in cryptocurrency seized in connection with him. Investigators noted that funds from a U.S. scam victim were traced back to a cryptocurrency account registered in his name.
The DSI's efforts are also targeting local officials, having referred cases involving seven electricity authority officials and a law enforcement officer to the National Anti-Corruption Commission. These individuals are suspected of facilitating the miners' illegal access to power.
This intensified inquiry is part of a broader initiative to combat electricity theft linked to cryptocurrency operations across the region. Similar issues have been reported in neighboring Malaysia, where approximately $1.1 billion in stolen electricity has been documented over the last five years.
