A Seattle-area man was sentenced to prison for laundering foreign fraud funds with Bitcoin and Ethereum. Here is what the case centers on and why it matters.
A Newcastle, Washington man was sentenced to five years in federal prison on June 9, 2026, for conspiracy to commit money laundering after funneling nearly $100 million in foreign fraud proceeds through dozens of bank accounts and cryptocurrency exchanges, converting the funds into Bitcoin, Ethereum, and other digital assets.
What Happened in the Seattle-Area Crypto Laundering Case
Geoffrey K. Auyeung, 47, received the sentence after pleading guilty to helping overseas fraudsters move money stolen through an oil-and-gas investment scheme, the U.S. Department of Justice said. This is a sentencing story, not a market event; it marks a completed criminal prosecution with a prison term now imposed.
What to Know
- A Seattle-area man was sentenced to five years in prison for laundering foreign fraud funds through Bitcoin, Ethereum, and other cryptocurrencies.
- Prosecutors say accounts he controlled received $97.1 million in fraud-linked deposits over a two-year period.
Between June 2022 and July 2024, accounts controlled by Auyeung received $97.1 million in domestic and international third-party wire transfers and other deposits that prosecutors described as fraud proceeds.
U.S. Attorney Charles Neil Floyd said Auyeung “facilitated a fraud, developed by others, that stole investor money.”
Auyeung admitted receiving at least $4,078,348 in commission payments for his role. Even after his indictment, he continued the scheme for 16 months by routing deposits through bank accounts held in his wife’s name, collecting an additional $400,000.
How Bitcoin and Ethereum Featured in the Laundering Scheme
Auyeung opened at least 81 bank accounts at 24 financial institutions and 19 accounts on eight cryptocurrency exchanges to move the funds. The scale of the account network underscores how the scheme relied on both traditional banking and crypto infrastructure.
Prosecutors said the fraud proceeds were converted into Bitcoin, Tether, USD Coin, and Ethereum through exchanges including Gemini, BitStamp, and Coinbase. Much of the cryptocurrency was then sent to Binance accounts controlled by individuals in Nigeria and Russia.
The crypto conversions were not incidental. They served as the key mechanism for moving value across borders and obscuring the funds’ origins. The use of multiple tokens across multiple exchanges made tracing the money more difficult for investigators, though federal agents ultimately reconstructed the full trail.
The case is distinct from recent crypto hacking incidents in that Auyeung was not exploiting protocol vulnerabilities. He was using legitimate exchange services as laundering tools for fraud proceeds that originated outside the crypto ecosystem entirely.
Why the Sentencing Matters for Crypto Fraud Enforcement
A sentencing carries more legal weight than an arrest or indictment. It means a court has imposed a definitive punishment, closing the criminal proceeding and establishing a precedent for similar cases.
The financial consequences extend beyond the prison term. The government sought $24,707,031 in restitution. Auyeung agreed to forfeit approximately $2.3 million in seized funds and not contest forfeiture of about $7.1 million in cryptocurrency through a related civil action.
The combined restitution and forfeiture stack, totaling over $34 million in claims, reflects a pattern in DOJ crypto enforcement: prosecutors increasingly pair prison sentences with aggressive asset recovery targeting both fiat and digital holdings.
The case was investigated by Homeland Security Investigations and IRS Criminal Investigation, agencies that have expanded their crypto-tracing capabilities as regulators globally tighten oversight of digital asset transfers. The cross-border dimension, with funds flowing to accounts linked to individuals in Nigeria and Russia through Binance, adds an international enforcement layer.
For the broader crypto industry, the case reinforces that exchanges operating within U.S. jurisdiction remain subject to anti-money laundering enforcement. Auyeung’s use of regulated platforms like Gemini and Coinbase did not shield the scheme from prosecution; it ultimately provided the transaction records that helped investigators build the case.
The sentencing arrives during a period of heightened scrutiny of crypto-linked financial crime, with federal prosecutors treating cryptocurrency rails as extensions of traditional money laundering infrastructure rather than a separate enforcement category.
