A pig butchering scheme has become the focus of a new U.S. federal case after prosecutors charged Vietnamese national Trung Nguyen Van, 37, with two counts of money laundering in connection with an alleged cryptocurrency fraud operation.
The charges were announced by the U.S. Attorney’s Office for the Western District of Missouri on September 25, 2026, following Van’s initial court appearance in Los Angeles.
According to prosecutors, one victim transferred approximately $16 million worth of cryptocurrency between June and August 2024 after being led to believe the funds were being invested through a platform called “Triangle.”
Investigators subsequently traced more than $569,000 of the victim’s funds to a cryptocurrency wallet associated with Van.
Pig butchering scheme allegedly targeted crypto investors
A pig butchering scheme generally relies on building trust with a target before introducing an investment opportunity. According to the U.S. Department of Justice, fraudsters may initially contact victims through dating platforms, social media, text messages or messaging applications.
The relationship can appear personal or romantic before the conversation gradually shifts toward cryptocurrency investments.
Victims may then be directed to websites designed to resemble legitimate trading or investment platforms. The websites can display fabricated profits, encouraging victims to commit increasingly larger amounts of money.
In the Missouri case, prosecutors allege that the victim was persuaded to use the “Triangle” platform and ultimately transferred roughly $16 million in cryptocurrency during a period spanning June through August 2024.
The funds were allegedly presented as investments rather than being recognized by the victim as payments to fraudsters. The U.S. Attorney’s Office said the case reflects the increasingly sophisticated nature of this type of fraud.
“Pig butchering schemes are an increasingly prevalent and sophisticated form of fraud that have caused billions of dollars in losses to victims around the world.”

Blockchain trail links funds to Van’s wallets
Court documents cited by federal prosecutors allege that a cryptocurrency transfer worth more than $569,000 reached a wallet associated with Van on August 7, 2024. Two days later, the same wallet allegedly received six additional transfers totaling approximately $569,569 that investigators traced back to the same victim.
Prosecutors allege that Van then moved approximately $567,999 through four transactions into a private, unhosted cryptocurrency wallet.
Such transfers can make the movement of assets more difficult to associate with a centralized service, although blockchain transactions themselves remain recorded on public ledgers depending on the network involved.
The investigation allegedly uncovered a much larger flow of cryptocurrency. From February 9, 2018, through December 17, 2024, wallets associated with Van reportedly received approximately $53.28 million in cryptocurrency connected to wire-fraud schemes targeting U.S. citizens.
Prosecutors say approximately $53.19 million was subsequently transferred to other accounts outside the centralized blockchain network.
The figures do not mean that every asset received by the wallets came from the single $16 million victim. Rather, prosecutors say the wallet activity was connected to multiple fraud schemes and additional victims.
Pig butchering scheme investigation involved FBI
The investigation was conducted by the Federal Bureau of Investigation, with prosecutors saying numerous U.S.-based victims reported losses associated with suspicious wallets that ultimately sent cryptocurrency to wallets linked to Van.
According to the criminal complaint, the victims described similar experiences. They were allegedly introduced to individuals online, encouraged to invest through particular websites and shown promises of substantial financial returns. When they attempted to withdraw their funds, they were ultimately unable to recover their investments.
Chris Ormerod, special agent in charge of the FBI’s Kansas City Field Office, said investigators worked with other agencies and private-sector partners to identify the alleged operation.
The FBI’s involvement illustrates the growing importance of cooperation between law enforcement and private blockchain-related companies when investigating cryptocurrency fraud.
Transactions can move rapidly across wallets and jurisdictions, requiring investigators to follow digital-asset flows alongside traditional financial evidence.
What the case means for crypto investors
The allegations surrounding this pig butchering scheme shows a key distinction for cryptocurrency investors: the existence of visible profits on an investment website does not necessarily demonstrate that the underlying assets are being invested.
Fake platforms can potentially display account balances or gains that have no connection to actual investments.
The U.S. case alleges that the victim believed they were participating in a cryptocurrency investment opportunity before investigators traced part of the funds to wallets associated with the defendant.
The case also demonstrates why unsolicited investment approaches deserve particular scrutiny. Online relationships that quickly develop into financial conversations, pressure to increase deposits, promises of unusually high returns and difficulties withdrawing funds are among the warning signs associated with this type of fraud.
At the same time, the allegations against Van remain allegations. The U.S. Attorney’s Office explicitly stated that the charges contained in the criminal complaint are accusations rather than evidence of guilt, and that evidence supporting the charges would have to be presented to a federal trial jury.
The investigation therefore remains a legal proceeding rather than a final determination of criminal liability.
For the cryptocurrency industry, however, the case adds to the growing body of enforcement activity surrounding investment fraud and the movement of illicit digital assets across blockchain networks.
