According to Cointelegraph, Larry Harmon, founder of the crypto mixer Helix, was arrested in 2020 for helping criminals launder money and has been sentenced to three years in prison. Beryl Howell, a judge in the District Court for the District of Columbia, said the sentence was lenient given his assistance in the Bitcoin Fog mixer case. Harmon was also ordered to forfeit approximately $311 million in cash, as well as more than $400 million worth of cryptocurrencies, real estate, and financial assets. Harmon operated the darknet Helix cryptocurrency mixer between 2014 and 2017, laundering more than 350,000 BTC during that period.
