FinCEN Assesses $60 Million Penalty in First Bitcoin Mixer Case

The Financial Crimes Enforcement Network on October 19, 2020 assessed a $60 million civil money penalty against Larry Dean Harmon, whom the agency identified as the founder, administrator and primary operator of the bitcoin mixing services Helix and Coin Ninja. FinCEN described the action as its first penalty against a bitcoin mixer, turning years of guidance about virtual-currency money transmission into a major public enforcement case.

The central development was regulatory, not a move in bitcoin’s market price. FinCEN determined that Harmon, doing business through Helix and Coin Ninja, willfully violated the Bank Secrecy Act’s registration, anti-money-laundering program and suspicious-activity reporting requirements. The assessment was an administrative enforcement finding by FinCEN. It was separate from the pending criminal case described below.

What the assessment established

FinCEN said Helix accepted bitcoin from customers and transmitted bitcoin to other people or locations while obscuring its source or ownership. The agency treated that activity as money transmission and therefore treated the operator as a money services business subject to Bank Secrecy Act obligations.

For the period from approximately June 6, 2014 through December 16, 2017, FinCEN reported that Helix conducted more than 1,225,000 customer transactions. It also said wallet addresses associated with Helix had sent or received more than $311 million, and that its investigation identified at least 356,000 bitcoin transactions through the service. Those measures are not interchangeable: one is a customer-transaction count, one is a dollar-value measure attached to associated addresses, and one is FinCEN’s identified bitcoin-transaction count.

The agency’s assessment said its review of public records and convertible-virtual-currency blockchains identified at least 245,817 instances of suspicious transactions from 2014 through 2017, while Helix filed no suspicious activity reports during the corresponding period. FinCEN also said the absence of an internal monitoring program made the complete number of reporting violations difficult to determine. These are FinCEN’s investigative findings, not an independently reproduced Coinburn on-chain calculation.

FinCEN’s document recorded that it sent Helix a pre-assessment notice on February 6, 2020. According to the agency, counsel responded on March 6, 2020 by denying that Helix operated as a money services business and seeking more time, but supplied no additional facts or documents before the October 19, 2020 assessment.

Why the case mattered

The action made the compliance boundary more concrete for the digital-asset industry. FinCEN’s May 9, 2019 guidance had distinguished an anonymizing service that accepts and retransmits customer value from a provider that merely supplies anonymizing software. Under that guidance, the first is a money transmitter; the software provider is not a money transmitter merely for supplying the tool.

That distinction matters because the October 19, 2020 action was not a declaration that privacy technology itself was prohibited. FinCEN’s case depended on the business activity it found: accepting and transmitting bitcoin for customers, operating without registration, maintaining no effective anti-money-laundering program and filing no suspicious activity reports. For exchanges, hosted wallets and other intermediaries, the institutional message was that cryptocurrency branding did not displace obligations attached to the underlying flow of customer funds.

The penalty also demonstrated that public blockchain analysis could support a Bank Secrecy Act case even when a service was designed to frustrate tracing. That was significant to compliance teams and investigators, but the assessment did not establish a same-day bitcoin price effect, and no such market claim is made here.

The parallel criminal case

The Justice Department had announced on February 13, 2020 that a three-count indictment against Harmon was unsealed on February 11, 2020. It charged money-laundering conspiracy, operating an unlicensed money-transmitting business and transmitting money without a District of Columbia license. On October 19, 2020 those criminal charges remained allegations, and Harmon was entitled to the presumption of innocence. FinCEN’s civil assessment did not itself resolve that prosecution.

As of October 19, 2020, the durable significance was narrower but substantial: the United States had applied existing money-transmitter rules to a custodial bitcoin mixing operation and imposed a $60 million penalty, while preserving a functional distinction between operating a transmission service and writing privacy software.
