Two other crypto criminals, including Larry Harmon, the former CEO of bitcoin mixer Helix, and Ilya Lichtenstein, who, along with his wife Heather “Razzlekhan” Morgan, laundered $3.6 billion in bitcoins from the 2016 Bitfinex hack, testified against Sterlingov during his trial. Lichtenstein pleaded guilty last August and has not yet been sentenced while Harmon pleaded guilty in 2021, agreeing to forfeit over 4,400 bitcoins and pay a fine of $60 million.
