Unveiling a Major Illegal Crypto Mining Network in Thailand

In a significant breakthrough, the Department of Special Investigation (DSI) in Thailand has uncovered an expansive illegal cryptocurrency mining network. This operation, reportedly linked with Chinese investors, is believed to be part of a broader scheme involving international money laundering and cybercrime activities. The investigation, which was initially focused on electricity theft, has now revealed deeper connections with transnational criminal operations.

From Electricity Theft to International Cybercrime

Throughout 2025, the DSI’s Office for Technology and Information Crime Investigations dismantled three major illegal crypto mining networks. During these operations, authorities seized over 6,390 mining devices. The damage caused by electricity theft alone exceeded 953 million baht ($28.5 million). Further investigations have unearthed links between these unlawful mining farms and a network of “grey” Chinese investors.
According to law enforcement officials, this structure may be implicated in laundering funds from fraudulent call centers and international online gambling platforms. Financial analyses suggest that companies and bank accounts associated with this network conducted transactions amounting to at least 10 billion baht yearly (approximately $300 million). Moreover, Myanmar citizens allegedly working for the organization were withdrawing cash ranging from 30 million to 50 million baht daily from Thai banks.

Arrests and International Collaboration

The DSI also announced receiving information from U.S. law enforcement concerning one of the case’s key figures—a Chinese national named Wang Yicheng. According to American sources, the U.S. Secret Service confiscated digital assets linked to Yicheng valued at over $17.8 million; meanwhile, total damages in this related investigation are estimated to exceed 2 billion baht (nearly $60 million).
Currently, eight suspects—four Chinese nationals and four Myanmar nationals—are facing arrest warrants issued by DSI. Authorities are preparing additional warrants for seven more individuals while five suspects have already been formally charged.
Additionally, the ongoing investigation has identified potential involvement by government officials in supporting the network’s operations. Two criminal cases have been forwarded to Thailand’s National Anti-Corruption Commission involving seven energy sector workers along with one law enforcement officer among others suspected of financing or aiding this criminal organization.

Broader Implications on Cryptocurrency Landscape

The DSI emphasized that illegal cryptocurrency mining not only constitutes electricity theft but also serves as a tool used by transnational crime groups for laundering money funding cybercrime activities as well as illicit capital movement across borders—a serious threat indeed posed towards economic stability plus financial security within countries involved.
