Rigs Seized and Power Stolen
Thai authorities have expanded an investigation into illegal cryptocurrency mining networks allegedly run by Chinese financiers that laundered more than $300 million (10 billion baht) annually through illicit cash operations. The Department of Special Investigation (DSI) announced that the transnational network utilized a complex financial web to funnel money from online gambling, call center scams and cyber fraud.
The move follows a series of raids in 2025 by the DSI’s Technology and Cyber Crime Bureau, which dismantled three major syndicates. At the time, investigators seized more than 6,390 crypto-mining rigs. According to a local report, the operations stole nearly $29 million worth of electricity from the Provincial Electricity Authority (PEA), making it one of the largest state utility thefts in Thailand’s recent history.
The probe has also ensnared local officials. The DSI has forwarded two cases to the National Anti-Corruption Commission targeting seven electricity authority workers, one law enforcement officer, and 13 investors and suspected accomplices accused of facilitating the operation.
According to investigators, the profits from these tech crimes were laundered through corporate entities and bank accounts experiencing unusually high volumes of cash flow. To move the assets, the network allegedly hired Myanmar nationals to make daily cash withdrawals from Thai banks ranging from $910,000 to $1.5 million per day, totaling at least $307 million a year.
The DSI added that U.S. law enforcement agencies provided intelligence tying a key figure in the operation, Wang Yicheng, to a major digital asset fraud scheme. The U.S. Secret Service previously seized more than $17.8 million in digital assets linked to Wang, part of a broader fraud scheme that caused nearly $61 million in total damages.
Thai authorities have issued arrest warrants for eight suspects, including four Chinese financiers and four Myanmar team members. They are seeking seven additional warrants and have summoned five others to face formal charges.
DSI officials stated that the illegal use of electricity for cryptocurrency mining has evolved past simple utility theft, serving as a vital mechanism for international criminal syndicates to fund cybercrime and destabilize the country’s economic and financial security.
Prosecutors are currently preparing the case file for trial.
