Thailand seizes 6,390 crypto mining rigs, issues arrest warrants in $300M laundering probe

Arrest warrants have been issued for eight suspects tied to a money laundering operation responsible for the laundering of over 10 billion baht ($300 million) per year in Thailand.

The eight individuals were involved in three, now dismantled, illegal cryptocurrency mining networks. This investigation is one of the largest crackdowns on illicit crypto infrastructure in Thailand. 

How did authorities in Thailand discover the $300 million per year money laundering scheme? 

During an electricity theft investigation in 2025, investigators discovered a larger financial network involving eight individuals who have now been issued arrest warrants.

The DSI is seeking seven additional warrants and has summoned five other individuals to face formal charges.

Thailand’s Department of Special Investigation (DSI) and Cyber Crime Bureau traced the illegal mining operations these individuals were involved in back to Chinese financiers who allegedly ran a sophisticated cash-laundering pipeline across the country.

Four of the warrants issued are for the Chinese financiers, while the others are for four Myanmar nationals who allegedly managed ground-level cash operations.

Authorities confiscated over 6,390 mining machines and estimated the networks stole 953 million baht (roughly $29 million) in electricity from the Provincial Electricity Authority (PEA).

The network obtained 30 million and 50 million baht per day in cash from phone scams and cross-border online gambling rings, pushing the operation’s annual financial throughput past the 10 billion baht mark.

The DSI reported that the corporate bank accounts connected to the network showed transaction volumes that are above what their stated business activities could explain.

The National Anti-Corruption Commission has received two case files from the DSI involving seven Provincial Electricity Authority employees, one law enforcement officer, and 13 investors or suspected accomplices accused of enabling the mining operations.

Investigators seized crypto hardware, cash, laptops, and bank passbooks from the residences of four PEA officials.

What is Wang Yicheng’s involvement in the case? 

Wang Yicheng has been identified by the DSI as a central figure in the money laundering network and is also a suspect in a U.S. digital asset fraud case.

The U.S. Secret Service has seized digital assets worth more than $17.8 million (around 620 million baht) in connection with Wang. The total damage exceeds 2 billion baht.

A cryptocurrency account registered in Wang’s name received more than $90 million in recent years, with at least $9.1 million traced by blockchain analysis firm TRM Labs to wallets associated with “pig-butchering” scams.

Wang served as vice-president of the Thai-Asia Economic Exchange Trade Association, a Bangkok-based Chinese trade group, in 2023. It has now shared that Wang left its board due to failure to pay membership dues and “personal reasons.” The group said its background checks on Wang found no criminal record.
