Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF PUERTO RICO

MICHAEL E. GUMPRECHT, LLC, Plaintiff, v. CIVIL NO. 24-1210 (JAG) MICHAEL GROFF and WESLEY DECATUR, Defendants.

OPINION AND ORDER GARCIA-GREGORY, D.J. Pending before the Court is Plaintiff Michael E. Gumprecht, LLC’s (“Plaintiff”)1 Motion for Summary Judgment. Docket No. 60. Plaintiff argues that Defendants Michael Groff and Wesley Decatur (“Defendants”) sold unregistered security contracts, the Mining Services Agreements (“MSAs”), in violation of the Illinois Securities Law Act of 1953 (the “Act”), 815 ILL. COMP. STAT. ANN 5/1 et seq. (West 2016). Docket No. 1 at 15-16. It also contends that Defendants are subject to control person and director liability under the statute and seeks class certification. Id. at 14-15. Plaintiff asserts jurisdiction under both the diversity statute and the Class Action

Fairness Act (“CAFA”), 28 U.S.C. § 1332(d), as “it is a putative class action in which more than $5,000,000 is in controversy.” Id. at 2; see Cooper v. Charter Commc’ns. Ents. I, LLC, 760 F.3d 103, 106 (1st Cir. 2014) (CAFA “grants jurisdiction to federal courts to hear state-law class actions if there

1 Plaintiff is a limited-liability company incorporated and headquartered in the State of Georgia. Docket No. 61-13 at 1. The Court shall refer to Michael E. Gumprecht, LLC as “Plaintiff” and shall refer to the individual Michael E. Gumprecht as “Gumprecht.” is minimal diversity of citizenship between the parties, as the parties agree there is here, and the amount in controversy exceeds five million dollars.”) (quoting 28 U.S.C. § 1332(d)(2)).2 Also before the Court is Defendants’ Cross-Motion for Summary Judgment. Docket No. 67. Defendants claim that Plaintiff wants the Court to rewrite “the terms of the bargain.” Id. at 6.

Per Defendants, the MSAs do not qualify as securities because Plaintiff had a wide latitude of control under the agreements. Id. at 6, 9-10. “These individual decisions inured to [Plaintiff’s] sole benefit. His Client Wallet went up or down based on his decisions, independently of any other Client’s performance or Supplybit’s overall performance.” Id. at 6. Alternatively, Defendants argue that Plaintiff’s “idiosyncratic reading of the MSAs—where he interprets them to have the opposite purpose and effect than what he declared in writing—presents a question of fact regarding the true, underlying economic reality of the MSAs.” Id. at 7. Defendant Decatur individually moves to dismiss the claims against him because he did not participate or aid in the sale of the alleged

security to Plaintiff. Id. at 28-29. For the below stated reasons, Plaintiff’s Motion for Summary Judgment is GRANTED IN PART and DENIED IN PART, and Defendants’ Cross-Motion for Summary Judgment is GRANTED IN PART and DENIED IN PART.

FACTUAL BACKGROUND I. Bitcoin Background Bitcoin, a virtual asset, is created on a “digital ledger” known as a “blockchain.” Docket Nos. 61 at 2; 68 at 1; 11 at 5. Blockchain is maintained through a network of computers that employ

2 “Here, although a class has not been certified, the district court [may] treat[] the complaint as asserting a class action.” Cooper, 760 F.3d at 106. CAFA applies “to any class action before or after the entry of a class certification order by the court with respect to that action.” 28 U.S.C. § 1332(d)(8). a cryptographic function known as a “hash.” Docket Nos. 61 at 2; 68 at 1; 11 at 5. A hash is used as a key, which validates a transaction—known as a “block”—and links this block to all prior transactions as part of a “chain.” Docket Nos. 61 at 2; 68 at 1; 11 at 5. On average, the quantity of hash deployed on a network is proportional to the speed in which Bitcoin is awarded or “mined.” Docket Nos. 61 at 2; 68 at 1; 11 at 5-6. Under an agreement known as a “mining pool,” a group can

combine their computing resources and share the successfully mined Bitcoin. Docket Nos. 61 at 2; 68 at 2; 11 at 6. The cost of deploying hash can be impacted by factors such as the cost of electricity and the efficiency of the computing, among others. Docket Nos. 61 at 2; 68 at 2; 11 at 6. Broadly, the cost of Bitcoin has increased since 2010. Docket Nos. 61 at 3; 68 at 2; 11 at 6. II. Supplybit LLC Supplybit LLC, a since dissolved Delaware limited liability company, was founded by its Chief Executive Officer, Defendant Groff, to mine Bitcoin for himself. Docket Nos. 61 at 3; 61-3 at 108; 61-12 at 4; 68 at 2-3. Defendant Decatur served as Chief Financial Officer and Managing Director. Docket Nos. 61 at 3; 61-3 at 52; 61-12 at 4; 68 at 3. Supplybit had two employees during the relevant period. Docket Nos. 61 at 3; 61-4 at 40; 68 at 2-3. Mining Bitcoin has inherent operational risks associated with it, which can make mining

challenging. Docket Nos. 61-3 at 99-100; 61 at 3; 68 at 3. Supplybit owned thousands of mining computers, valued at $40.2 million in 2022, to support its Bitcoin mining operation. Docket Nos. 61 at 4; 61-3 at 97; 61-5 at 41; 61-6 at 60; 61-7 at 16; 68 at 4. Supplybit would generate hash power through mining equipment it owned. Docket Nos. 61-3 at 11; 61-6 at 149. The company utilized Luxor, a third-party mining pool, to generate additional hash power. Docket No. 61-3 at 44-45. Supplybit’s clients signed an MSA. Docket Nos. 61 at 4; 61-3 at 10; 68 at 4. Supplybit did not register the MSA as a security under federal or state law. Docket Nos. 11 at 2; 61 at 5; 61-5 at 70. Wire and cash payments made by clients would be placed into Supplybit’s bank account. Docket No. 61-5 at 46-47. III. The Mining Services Agreements The MSAs governed the relationship between Supplybit and its clients. See Docket Nos.

61-10, § 9.15 (“This Agreement constitutes the entire agreement between the Parties as to the subject matter described herein and supersedes any prior agreements, understandings, representations, warranties, and restrictions between the Parties that relate to such subject matter.”); 61-11, § 9.15 (same). All parties to the MSA were to be treated as independent contractors. Docket Nos. 61-10, § 9.01; 61-11, § 9.01.3 Under the MSAs, clients “purchased” or “leased” mining power. Docket Nos. 11 at 1; 61 at 5; 61-5 at 83. Mining power is the amount of hash per second deployed for the mining of a cryptocurrency. Docket Nos. 61-10, §§ 1.29, 1.49; 61-11, §§ 1.29, 1.49. Clients additionally could sell a miner, known as a Trade-In Miner, to Supplybit to increase their current max mining power under the agreement. Docket Nos. 61-10, § 1.54; 60-11, § 1.54. Trade-In Miners were subjected to a testing period in which Supplybit would calculate the miner’s observed mining power, observed

running cost rate, and expiration date, and inform the client of its determinations. Docket Nos. 61-10, §§ 1.51, 3.08; 61-11, §§ 1.51, 3.08. Clients’ mining power would be automatically directed towards the mining of Bitcoin, unless the client stated otherwise. Docket Nos. 61-10, § 3.01(e); 61-11, § 3.01(e). Notwithstanding, the MSAs provide that [A client] shall have no right to specific performance under this Agreement such as might compel Supplybit to operate any particular Miners in any particular fashion or to deploy any particular amount of Mining Power, Client’s rights under this
