Summary

Geoffrey K. Auyeung of Newcastle, Washington, was sentenced to five years in prison for conspiracy to commit money laundering after prosecutors said he helped move $97.1 million from an investment scam through a network of 81 bank accounts, 19 crypto exchange accounts and at least nine entities. The funds were routed through Gemini, Coinbase and BitStamp and converted into BTC, ETH, USDT and USDC, according to the U.S. Department of Justice as cited by The Block. Prosecutors said he earned at least $4 million from the scheme and another $400,000 after he was indicted. The case highlights how fraud proceeds can be layered through both traditional banking channels and liquid digital assets to complicate tracing and recovery.
