US DOJ Seizes and Freezes $580 Million in Crypto Linked to Chinese Criminal Groups

Transnational criminal organizations based in Southeast Asia operate industrial-scale compounds that use fake romantic, social or business relationships to steer victims into fraudulent digital-asset investments. The schemes rely on counterfeit trading platforms, shell companies, money mules and professional laundering networks, often moving proceeds through stablecoins and overseas crypto exchanges. Their scale has made crypto investment fraud a major cross-border threat to US consumers and the financial system.

The Financial Crimes Enforcement Network, or FinCEN, released its analysis and an industry alert on Sept. 3, 2026. It reviewed 33,904 Bank Secrecy Act reports filed from Sept. 8, 2023, through Dec. 31, 2025, identifying about $12.7 billion in suspected scam-related financial activity. Money services businesses, including crypto firms, submitted more than half of the reports and accounted for roughly $5.5 billion, while banks reported the largest dollar total at $6.4 billion.

Cryptocurrency investment and romance scams typically use fake trading platforms, fabricated relationships or bogus recovery services to win victims’ trust, then route proceeds through layers of digital wallets. The five cases span victims in the United States and Canada and alleged laundering networks centered in Southeast Asia. They underscore both the cross-border reach of crypto-enabled fraud and authorities’ ability to trace blockchain transactions and freeze assets through civil forfeiture proceedings.

On July 21, 2026, the U.S. Attorney’s Office for the District of Columbia and the U.S. Secret Service’s Washington Field Office filed five civil forfeiture complaints seeking more than $25 million in seized cryptocurrency. The two largest claims cover about $12.09 million linked to romance scams affecting more than 200 victims and $10.40 million traced to more than 270 suspected victim transactions. Three other complaints seek about $2.39 million, $1.23 million and $285,000. The investigations remain open, and the recoveries lifted the Scam Center Strike Force’s total above $800 million.

As cross-border online fraud grows more sophisticated, cryptocurrencies have become a new conduit for illicit money laundering because of their high degree of anonymity. Interpol has stepped up enforcement to prevent criminal groups from using decentralized finance to legitimize illicit proceeds. The scale and cross-border reach of such networks have made stemming virtual-asset flows a major challenge for global financial-security and law-enforcement authorities.

Interpol said in July 2026 that Operation First Light 2026 had dismantled a money-laundering network linked to romance scams. Thai police arrested two suspects whose cryptocurrency wallets received more than $122 million over 10 months. The coordinated global operation resulted in 5,811 arrests and the seizure of $293 million in illicit assets.

Scam compounds in Southeast Asia often target victims worldwide through romance scams and fraudulent investment schemes, and are linked to human trafficking and forced labor. The U.S. Department of Justice established the Scam Center Strike Force to trace cross-border fund flows alongside the FBI, the Secret Service and the Royal Thai Police. Platforms including Coinbase can use blockchain records to locate assets, making them a key part of efforts to disrupt scam networks.

A “week of action” beginning May 18, 2026, brought together Meta, Microsoft, Coinbase, Starlink and law enforcement agencies from multiple countries. Results announced on June 3 showed that Coinbase had frozen more than $3 million in crypto assets, Meta had disabled more than 1.4 million accounts, pages and groups, and Microsoft had suspended about 20,000 scam-related accounts. Thai police also arrested 63 suspects.
