Ohio man Gary James Harmon has been sentenced to 51 months in prison for stealing 712 BTC worth over $21 million from his brother, Larry Dean Harmon, who was arrested in February 2020 for operating a coin-mixing service called Helix. Gary James Harmon recreated Bitcoin wallets with his brother's credentials, "covertly" sending himself 712 BTC from a seized cryptocurrency storage device, and laundered the assets further.

Harmon pleaded guilty to wire fraud and obstruction of justice, and agreed to forfeit cryptocurrencies including 17.4 million Dogecoin, around 647 BTC, and just over 2 ETH.
