Larry Dean Harmon of Akron, Ohio, admitted operating a darknet site called Helix, which acted as a cryptocurrency money laundering service from 2014 to 2017. Helix functioned as a bitcoin mixer and “tumbler” for darknet users who wanted to hide the origins of their virtual currency, federal prosecutors say. Harmon also admitted he helped launder so-called “dirty” bitcoins in exchange for a transaction fee. He now faces up to a 20-year federal prison sentence and a $500,000 fine.”]
