UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA

UNITED STATES OF AMERICA

v. Criminal Action No. 19-395 (BAH)

LARRY DEAN HARMON, Chief Judge Beryl A. Howell

Defendant.

MEMORANDUM OPINION

Defendant, Larry Dean Harmon, is charged in three counts related to his alleged

operation of Helix, an underground tumbler for bitcoin, a form of virtual currency. See

Indictment (Dec. 3, 2019) at ¶¶ 3, 8–9, ECF No. 1. As described in the indictment, Helix

“enabled customers, for a fee, to send bitcoins to designated recipients in a manner which was

designed to conceal and obfuscate the source or owner of the bitcoins.” Id. ¶ 4. This service,

which was located on the Darknet — a collection of hidden websites accessible only to

anonymized users — was allegedly “advertised . . . as a way to” mask drug, gun, or other illegal

“transactions from law enforcement.” Id. ¶ 5. Between 2014 and 2017, Helix was used to

“exchange[] . . . approximately 354,468 bitcoins — the equivalent of approximately $311 million

in U.S. dollars.” Id. ¶ 8. On December 3, 2019, a federal grand jury in the District of Columbia

indicted defendant for conspiracy to launder monetary instruments, in violation of 18 U.S.C.

§ 1956(h), id. ¶¶ 14–16 (Count One); operating an unlicensed money transmitting business, in

violation of 18 U.S.C. § 1960(a), id. ¶¶ 17–18 (Count Two); and engaging, without a license, in

the business of money transmission, as defined in D.C. Code § 26-1001(10), in violation of the

District of Columbia’s Money Transmitters Act (MTA), D.C. Code § 26-1023(c), id. ¶¶ 19–20

1 (Count Three). Defendant has now moved to dismiss, for failure to state an offense, see FED. R.

CRIM. P. 12(b)(3)(B)(v), both Counts Two and Three, see Def.’s Mot. to Dismiss, ECF No. 31;

Def.’s Mem. Supp. Mot. to Dismiss (“Def.’s Mem.”), ECF No. 31. The motion to dismiss raises

two novel questions: Is bitcoin “money” for purposes of the District of Columbia’s MTA? Was

Helix, which operated as a bitcoin tumbler, an “unlicensed money transmitting business” under

18 U.S.C. § 1960(b)(1)(B)? After examination of the relevant statutes, case law, and other

sources, the Court concludes that bitcoin is money under the MTA and that Helix, as described in

the indictment, was an “unlicensed money transmitting business” under applicable federal law.

Accordingly, defendant’s motion to dismiss Counts Two and Three is denied.

I. BACKGROUND

The facts and charges in the indictment are summarized below, after a brief review of the

operation of bitcoin and the Darknet.

A. Technical Primer on Bitcoin and the Darknet

Brief primers on bitcoin and the Darknet are helpful to understand the charged activity

that is the focus of defendant’s pending motion to dismiss.

1. Bitcoin

“Bitcoin is a decentralized form of electronic or digital currency that exists only on the

[i]nternet.” United States v. Lord, 915 F.3d 1009, 1013 n.1 (5th Cir. 2019); see also United

States v. Brown, 857 F.3d 334, 337 (6th Cir. 2017) (defining bitcoin as “a virtual, sovereign-free

currency”); United States v. Costanzo, 956 F.3d 1088, 1091 (9th Cir. 2020) (“Bitcoin is an

alternative currency that can be transferred electronically anywhere in the world with no bank

and no government forms.”); United States v. Gratkowski, No. 19-50492, 2020 WL 3530575, at

*1 (5th Cir. June 30, 2020) (“Bitcoin is a type of virtual currency.”). The term bitcoin refers to

both a system and a unit. As a system, Bitcoin is a peer-to-peer network enabling proof and

2 transfer of ownership — of units, or tokens, also called bitcoin — without involving a third-party

such as a bank. See Eric D. Chason, How Bitcoin Functions As Property Law, 49 SETON HALL

L. REV. 129, 139 (2018) (“[T]he Bitcoin system comprises both a protocol for transferring

ownership and a set of records of all transactions.”); THE LAW OF BITCOIN 30 (Stuart Hoegner

ed., 2015).1 Conventionally, the Bitcoin network and its protocols are referred to with a capital

B, while the units transmitted on the network are referred to with a lowercase b.

Transferring or otherwise using a bitcoin requires an address, a public encryption key,

and a private encryption key. “Units of [b]itcoin are stored by reference to” the “address[].”

Shawn S. Amuial, Josias N. Dewey & Jeffery R. Seul, The Blockchain: A Guide for Legal &

Business Professionals § 1:3 (2016). The address, “similar to a bank account number, . . . is a

long string of letters and numbers.” Gratkowski, 2020 WL 3530575, at *1; see also Chason,

supra, at 141 (analogizing the address to a user name). Every address is associated with a public

key. See Chason, supra, at 141. Every public key is derived from a private key. Importantly,

private keys are secret, like passwords. See id. at 143 (“Private keys create public addresses, but

public addresses do not reveal the associated private keys.”).

To transfer bitcoin from one address to another, the sender transmits a message — called

a transaction — on the Bitcoin public network, and that transaction is eventually recorded on a

blockchain, a public ledger that records every bitcoin transaction. See Gratkowski, 2020 WL

3530575, at *1; THE LAW OF BITCOIN, supra, at 31.2 The transaction must contain: (1) the

1 Peer-to-peer “mean[s] that the computer servers, commonly called ‘nodes,’ that actively run” the Bitcoin network’s “open-source software are linked together.” Henry S. Zaytoun, Comment, Cyber Pickpockets: Blockchain, Cryptocurrency, and the Law of Theft, 97 N.C. L. REV. 395, 403 (2019). 2 Blockchain is a type of digital ledger. See Brittany Manchisi, What is Blockchain Technology?, BLOCKCHAIN PLUSE: IBM BLOCKCHAIN BLOG (July 31, 2018), https://www.ibm.com/blogs/blockchain/2018/07/what-is-blockchain-technology/; Bitcoin 101: What is Bitcoin?, COINDESK (Jul. 6, 2020), http://coindesk.com/learn/bitcoin-101/what-is-bitcoin (calling the Bitcoin network “distributed ledger that maintains the balances of all token trading”).

3 amount of bitcoin to be transferred; (2) the address to which the bitcoin will be sent; (3) the

address from which the bitcoin is being sent; and (4) the public key associated with the sender

and the sending address. See The Blockchain: A Guide for Legal & Business Professionals

§ 1:3; see also Chason, supra, at 147–48. With these elements in place, the sender must sign the

transaction using a digital signature generated using the sender’s private key. Id.; see also THE

LAW OF BITCOIN, supra, at 31. Once signed, the transaction is broadcast to the Bitcoin network.

The network then verifies the transaction by confirming that (1) the public key is

associated with the address of the sender and (2) the digital signature was produced for this

transaction using the sender’s private key. See Chason, supra, at 150; THE LAW OF BITCOIN,

supra, at 31. After the transaction is verified, the bitcoin being sent becomes associated with the

recipient address and its attendant private and public keys. See The Blockchain: A Guide for
