Simply put
- Helix processed over $311 million in Bitcoin and operated without registration as a mixer.
- A judge handed down a final forfeiture order in late January that transferred Helix’s assets to the U.S. government.
- Prosecutors allege that the service pooled and redistributed Bitcoin to disguise transactions linked to darknet market users.
U.S. authorities have seized more than $400 million in assets associated with Helix, a crypto mixer utilized for laundering money from online drug sales and other illegal activities.
The government took control of these assets last week, following a final court order issued on January 21.
Helix, which began operating in 2014, managed to handle approximately 354,468 Bitcoins at one point—valued at around $311 million back then.
Much of the virtual currency processed came from or moved into darknet drug markets, with the operators retaining a share as fees for using Helix, the Justice Department noted.
Mixing services like Helix act as tools for darknet marketplaces, mixing funds to obscure the original source and making transactions hard to track. The darknet refers to parts of the internet accessed through specialized tools like Tor for anonymity.
Helix’s operator, Larry Dean Harmon, created a platform that integrated closely with major darknet markets, earning fees from transactions investigators later traced back to tens of millions of dollars, according to the Justice Department.
“Helix was explicitly designed to facilitate laundering from darknet markets, not just a neutral privacy enhancer,” stated Ari Redboard, head of policy and government at TRM Labs. He added that dismantling this service is akin to removing a key laundering hub, which might push illegal actors to less straightforward and riskier options.
“While it might seem like a game of whack-a-mole, each shutdown introduces real obstacles to laundering, complicating the process and making it slower and riskier,” he remarked.
Case
The civil case against Harmon stemmed from breaches of the Bank Secrecy Act related to Helix’s operations from 2014 to 2017.
Prosecutors claimed Harmon ran Helix as an unregistered money services business, hiding the origin of Bitcoin transactions and facilitating over 1.2 million transfers exceeding $311 million.
Additionally, the court filing alleged that Harmon neglected to register Helix with the Financial Crimes Enforcement Network and failed to implement an anti-money laundering program, among other lapses.
Later, Harmon became CEO of CoinNinja, a registered money services business providing virtual currency exchange alongside mixing services.
His company’s DropBit product was promoted as a way to transfer Bitcoin through text messages and social media, circumventing KYC requirements.
Authorities also highlighted that Helix was utilized for various crimes, including drug sales, fraud, and child exploitation.
The civil suit came after Harmon faced a criminal case where he was indicted in 2019 and later pleaded guilty to conspiracy charges in 2021 concerning money laundering. Civil penalties imposed in October 2020 remain unpaid.
