Federal Fraud Investigation and Sentencing
In a significant federal fraud investigation, authorities have confiscated millions in cryptocurrency linked to a scheme involving nearly $100 million. This operation led prosecutors to secure a five-year prison sentence for Geoffrey K. Auyeung, the mastermind behind the fraudulent activities, according to statements made by the U.S. Attorney’s Office for the Western District of Washington on June 9, 2026.
Details of the Fraudulent Scheme
The investigation uncovered that Auyeung had lured victims through fake investments in oil and gas storage projects based in Rotterdam, Netherlands, and Houston, Texas. The victims mistakenly believed they were depositing money into escrow accounts; however, those funds were promptly transferred to other accounts or used to acquire various cryptocurrencies such as Bitcoin, Ethereum, and Tether via major cryptocurrency exchanges including Coinbase, Bitstamp, and Gemini. The Department of Justice (DOJ) provided insights into this flow of money, asserting that much of it was later deposited into Binance accounts.
Scale of the Financial Deception
Court documents reveal that Auyeung opened a staggering 81 bank accounts across 24 different financial institutions, as well as 19 accounts on various cryptocurrency platforms. Between June 2022 and July 2024, a total of $97.1 million was processed through these accounts, reflecting the extensive scale of the financial deception.
Describing cryptocurrency as a major instrument for laundering the misappropriated funds, the DOJ emphasized that victim investments ultimately led to money being funneled into various offshore accounts and used to facilitate transactions with co-conspirators located abroad.
Restitution and Financial Liabilities
Currently, victims are engaged in a lengthy restitution process, with prosecutors pursuing $24,707,031 to compensate for their losses. One victim even traveled from the UK to personally confront Auyeung during the sentencing.
Auyeung’s financial liabilities extend beyond the prison sentence; he has forfeited approximately $2.3 million in seized funds and cash from his residence, alongside the seizure of an Audi SQ8. Additionally, he consented to surrender around $300,000 in bank holdings as part of the restitution agreement and has also agreed to comply with the civil forfeiture of $7.1 million taken from various cryptocurrency wallets.
Ongoing Investigations and Implications
Moreover, the DOJ reported that Auyeung allegedly maintained communication with accomplices even after his indictment and arrest. From August 2024 until December 2025, he received upwards of $400,000 in commission payments funneled through accounts registered in his wife’s name.
This case represents a landmark moment for the DOJ, marking one of the largest cryptocurrency forfeitures in history, which has consequently intensified the scrutiny of global scam operations linked to crypto fraud, human trafficking, and organized crime.
