The DSI said on June 19 that the expanded probe now covers a network it links to Chinese investors who allegedly used large-scale crypto mining operations to launder proceeds from scams and online gambling. The agency said it had issued eight arrest warrants and was seeking seven more. For related coverage, see Scott Bessent Says Crypto Market Structure Bill Is Essential.
What Thai Authorities Say the Expanded Investigation Covers
The DSI said its 2025 crackdown dismantled three major illegal mining networks and seized more than 6,390 crypto-mining machines. The agency estimated that damage to the Provincial Electricity Authority from the stolen power exceeded 953 million baht.
Associated bank accounts and entities showed at least 10 billion baht in annual turnover, the DSI said. The agency added that Myanmar nationals were allegedly used to withdraw approximately 30-50 million baht in cash per day from Thai financial institutions tied to the network.
Reuters reported on June 25 that Thai authorities had issued an arrest warrant for Wang Yicheng, described by the DSI as a key figure in the alleged network. DSI spokesperson Police Major Woranan Srilam said Wang had been charged in November with theft and offenses under Thailand’s Computer Crimes Act, and that authorities believed he had fled the country.
A 2023 Reuters investigation found that a crypto wallet in Wang’s name received at least $9.1 million between 2021 and 2022 from an account that TRM Labs and other blockchain analysis firms linked to pig-butchering scams.
Why the Crypto Mining and Money Laundering Allegations Matter
The case ties together electricity theft, illicit crypto mining, and large-scale cash laundering in a single alleged operation, a combination that elevates it beyond a routine fraud case. The DSI’s figures suggest an operation with industrial-scale financial throughput.
Thailand has been stepping up enforcement actions targeting crypto-linked financial crime. Authorities previously froze millions of bank accounts in a broader scam crackdown, and the country has also enforced measures to curb illegal flows through gold and crypto channels.
The cross-border dimension adds complexity. The DSI described the network as involving “grey Chinese capital,” and the alleged use of Myanmar nationals for daily cash withdrawals points to a multi-jurisdictional laundering structure that spans at least three countries.
The case also intersects with a broader global enforcement trend. U.S. authorities have separately seized infrastructure tied to billions in crypto laundering linked to Southeast Asian crime networks, underscoring the region’s growing role as a hub for crypto-linked financial crime.
What the Expanded Probe Could Mean for Crypto Oversight in Thailand
The expansion from a narrow electricity-theft case into a full cross-border money laundering investigation signals that Thai authorities view crypto mining operations as potential front-ends for larger financial crime networks, not just power-theft schemes.
The DSI said it had already referred related corruption cases to Thailand’s National Anti-Corruption Commission, suggesting the investigation could widen further. Meanwhile, the Thailand SEC has been weighing rule changes for crypto firms, reflecting a regulatory environment in active flux.
With 15 total arrest warrants either issued or sought and Wang Yicheng believed to have fled the country, the case remains open. Whether Thai authorities can secure extradition or asset recovery across borders will likely determine the investigation’s ultimate impact on regional crypto enforcement.
