The Financial Crimes Enforcement Network of the US Treasury Department has traced roughly $12.7 billion in questionable financial transactions to cryptocurrency investment fraud schemes operated predominantly from criminal facilities in Southeast Asia.
The agency examined 33,904 Bank Secrecy Act compliance filings submitted by approximately 1,300 financial institutions during the period spanning September 2023 through December 2025. American victims from all 50 states and multiple US territories were impacted by these fraud operations.
These fraudulent operations are known by various terms, including pig butchering scams, romance baiting schemes and cryptocurrency confidence fraud. Organized crime networks establish fabricated relationships with targets before directing them toward illegitimate crypto trading platforms.
Report submissions increased consistently throughout the analyzed timeframe. During October 2023, financial institutions filed 590 reports totaling $485.7 million. This figure surged to 2,482 reports representing $833.5 million by December 2025, demonstrating average monthly growth of 10.9% in report volume and 18% in monetary value.
Transaction Flow Patterns
Fraud victims acquired no fewer than 22 distinct cryptocurrencies, with Ethereum, Tether USDT and Circle USDC representing the most frequently purchased tokens. However, blockchain forensics revealed that criminal proceeds were invariably converted into USDT regardless of the original purchase.
Subsequently, these assets were channeled through decentralized finance applications or cryptocurrency exchanges operating beyond US jurisdiction. Certain collection wallets received simultaneous deposits from numerous victims, enabling investigators to connect disparate transactions to unified criminal networks.
FinCEN emphasized that the $12.7 billion figure should not be interpreted as the definitive total of victim losses. This amount may encompass blocked transaction attempts, redundant report submissions and reporting inaccuracies.
Fraud victims often depleted resources beyond their liquid savings. FinCEN recorded instances involving retirement portfolios, home equity credit lines and consumer loans. One victim withdrew approximately $640,000 from her retirement savings. Another individual lost over $1 million across a six-month period.
Criminal Operations in Southeast Asia
Numerous criminal syndicates maintain operations within extensive facilities throughout Cambodia, Laos and Burma. Workers are enticed through deceptive employment opportunities and subsequently coerced into contacting victims and executing fraudulent schemes.
United Nations assessments indicate hundreds of thousands of individuals have been subjected to human trafficking into these criminal enterprises. Chainalysis released a February 2026 analysis showing cryptocurrency payments connected to human trafficking increased 85% throughout 2025.
Law enforcement agencies have targeted the supporting financial systems. This past March, the FBI collaborated with Thai law enforcement to freeze approximately $580 million in digital assets and confiscate roughly 8,000 mobile devices connected to pig butchering operations.
The Cambodia-based Huione network emerged as a prominent illustration of enabling infrastructure. Chinese law enforcement detained a former Huione Group executive in April following investigations connecting the organization to more than $89 billion in cryptocurrency transactions.
FinCEN’s Rapid Response Program has successfully blocked $1.8 billion since its 2015 inception and recovered slightly over $1 billion for 5,790 American victims. The department advised anyone targeted by such schemes to immediately notify their financial institution and submit a formal complaint through the FBI’s Internet Crime Complaint Center.
