Bitcoin mixer operator sentenced to 3 years for laundering over $300m

As an analyst with over two decades of experience in financial crime investigations, I find Larry Harmon’s case to be a stark reminder of the dark side of innovation. The anonymous nature of cryptocurrencies, while revolutionary, can unfortunately serve as a shield for criminal activities when misused.


Larry Harmon, a resident of Ohio, was given a three-year prison sentence due to his involvement in washing over $300 million in Bitcoin using his darknet platform known as Helix, as reported by Bloomberg.

This platform ran a device meant for concealing the sources of cryptocurrency transactions, making it easier for its main users, who were predominantly criminals, to transfer money without being traced, as stated by the U.S. Justice Department.

From 2014 to 2017, the service was operational. During this period, Harmon collaborated with prominent darknet marketplaces such as AlphaBay for handling illicit transactions, which included drug deals, selling of stolen data, and counterfeit products.

Unlicensed money-transmitting

In the year 2021, Harmon admitted his guilt for running Helix as an unlicensed money-transfer service and for conspiring to launder funds. According to authorities, by blending more than 350,000 Bitcoins (BTC), he aided in carrying out illegal activities on a global level.

In addition to facing a fine of $60 million from the U.S. Treasury for breaking anti-money laundering laws, U.S. District Judge Beryl Howell has additionally demanded that Harmon give up $311 million, which represents the worth of the Bitcoin that was laundered using Helix.

Darknet mixers like Helix appeal to criminals seeking to exploit the pseudonymous nature of cryptocurrencies. While Bitcoin transactions are recorded on a public ledger, mixers obscure their origins by breaking the link between sender and recipient, complicating law enforcement efforts to trace illicit activities.

Harmon’s aid in various legal proceedings, such as the trial of Roman Sterlingov (Bitcoin Fog mixer), significantly contributed to a lenient sentencing. Prosecutors emphasized Harmon’s substantial help and believed that his case would discourage similar activities from occurring.

Moreover, it wasn’t just Larry Harmon who was implicated in this case. Following his arrest in 2020, it was found that his brother, Gary Harmon, had exploited the situation by using illicitly obtained credentials to retrieve Bitcoin from an IRS evidence vault, as reported by Bloomberg.

In the end, Gary received a four-year prison term due to illegally using and purchasing high-end goods with some of the confiscated digital currency.
