Opinion

UNITED STATES DISTRICT COURT CENTRAL DISTRICT OF ILLINOIS ROCK ISLAND DIVISION

ALEXANDER MARUYAMA, ) ) Plaintiff, ) ) v. ) Case No. 4:22-cv-04124-SLD-RLH ) JUSTIN LANDI, ) ) Defendant. )

ORDER Before the Court are Plaintiff Alexander Maruyama’s Motion for Summary Judgment, ECF No. 51, and Defendant Justin Landi’s Motion for Summary Judgment, ECF No. 50. For the following reasons, Plaintiff’s motion is DENIED, and Defendant’s motion is GRANTED. BACKGROUND1 Plaintiff entrusted Defendant to run his cryptocurrency mining equipment. This case arises out of the breakdown of Plaintiff and Defendant’s business relationship and Plaintiff’s allegations that Defendant committed wrongdoing both during and after their relationship came to an end. Neither party explains what cryptocurrency mining is, and the Court finds that a short explanation is warranted to provide context to the parties’ arguments. Cryptocurrency is “[a] digital or virtual currency that is not issued by any central authority” and that is “designed to function as a medium of exchange.” Cryptocurrency, Black’s Law Dictionary (12th ed. 2024).

1 At summary judgment, a court must “constru[e] the record in the light most favorable to the nonmovant.” Payne v. Pauley, 337 F.3d 767, 770 (7th Cir. 2003). Unless otherwise indicated, this background has been drawn from Plaintiff’s statement of undisputed material facts, Pl.’s Mot. Summ. J. 3–8; Defendant’s response thereto, Def.’s Resp. 2–8, ECF No. 53; Defendant’s statement of undisputed material facts, Br. Supp. Def.’s Mot. Summ. J. 2–9, ECF No. 50-1; Plaintiff’s response to Defendant’s statement of facts and Plaintiff’s statement of additional facts, Pl.’s Resp. 3– 19, ECF No. 52; Defendant’s reply to Plaintiff’s additional facts, Def.’s Reply 2–3, ECF No. 55; and exhibits to the filings. Cryptocurrency mining “is how some cryptocurrencies . . . process transactions and mint new [digital] tokens.” Allie Grace Garnett, What is crypto mining and how does it work?, Britannica Money, https://www.britannica.com/money/what-is-crypto-mining (last visited Sept. 29, 2025). A blockchain is the data structure through which cryptocurrency transactions are identified,

tracked, and shared across networks of computers, working as a digital ledger. Id. For a blockchain to track cryptocurrency transactions, the transactions must be verified by independent blockchain participators. Id. Blockchain verifiers, also known as cryptocurrency miners, are given the chance to verify cryptocurrency transactions by solving complicated mathematical problems. Id. The first miner to solve the problem and then verify the transaction on the blockchain is rewarded with a small amount of cryptocurrency. Id. Miners rely on advanced and specialized computer hardware to successfully mine cryptocurrency before others can secure the cryptocurrency reward for themselves. Id. Because cryptocurrency mining is technologically complex and requires advanced equipment, one of a miner’s biggest expenses is electricity, and miners work to reduce their power bills by locating their operations in areas with inexpensive

and reliable access to high amounts of electricity, see id., which is part of why this case is in the Central District of Illinois, cf. Landi Dep. 28:13–23, Pl.’s Mot. Summ. J. Ex. A, ECF No. 51-1 (testifying that Plaintiff sent mining equipment to East Moline, Illinois because electricity was cheaper in East Moline than in Japan where Plaintiff lives). Plaintiff is a citizen of Japan and Defendant is an Illinois resident—the two met in Japan in 2017 while Defendant was traveling with friends. Plaintiff and Defendant discussed their mutual interest in cryptocurrency, and Defendant built a mining rig in Plaintiff’s apartment to demonstrate what the process looked like. Later in 2017, Plaintiff and Defendant entered into an agreement pursuant to which Defendant built and managed Plaintiff’s cryptocurrency mining equipment in a warehouse in East Moline, Illinois. Defendant owns and controls Quad Cities Ethereum Mining (“QCEM”). His previous business partner, Mark Redeker, owns Twin Titans, LLC (“Twin Titans”). Both QCEM and Twin Titans owned and/or controlled Coingen, LLC (“Coingen”), the entity that owned the warehouse where Plaintiff’s equipment was stored. In

2021, Plaintiff and Defendant modified their agreement to include that Defendant would receive at least ten percent of the monthly profits earned by Plaintiff’s equipment. Defendant had access to Plaintiff’s “payout sites” for different types of cryptocurrencies, like Ethereum (“ETH”), Ethereum Classic (“ETC”), and Litecoin (“LTC”). Pl.’s Mot. Summ. J. 4; Def.’s Resp. 3, ECF No. 53. In his role, Defendant generally oversaw the function of the miners while Plaintiff could see whether his miners were “online” or not through various websites. The parties operated under this agreement until March 2022. At that time, Plaintiff terminated the business relationship. He filed this lawsuit six months later, bringing four claims against Defendant for conversion, fraud, breach of fiduciary duty, and breach of an oral agreement. See generally

Compl., ECF No. 1. The parties both move for summary judgment on all claims. Pl.’s Mot. Summ. J. 3; Def.’s Mot. Summ. J. 1–2.2 The briefing on both motions is complete. See generally Br. Supp. Def.’s Mot. Summ. J., ECF No. 50-1; Def.’s Resp.; Pl.’s Resp., ECF No. 52; Def.’s Reply, ECF No. 55; Pl.’s Reply, ECF No. 54. DISCUSSION I. Legal Standard Summary judgment should be granted “if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.

2 Defendant’s summary judgment motion, brief in support of summary judgment motion, and reply are all unpaginated; therefore, the Court uses the page numbers generated by CM/ECF when referring to these documents. R. Civ. P. 56(a). At the summary judgment stage, the court’s function is not to weigh the evidence and determine the truth of the matter, but to determine whether there is a genuine issue for trial—that is, whether there is sufficient evidence favoring the non-moving party for a factfinder to return a verdict in its favor. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 249

(1986). The court must view the evidence in the light most favorable to the non-moving party and draw all reasonable inferences in that party’s favor. McCann v. Iroquois Mem’l Hosp., 622 F.3d 745, 752 (7th Cir. 2010) (citing Anderson, 477 U.S. at 255). “A genuine issue for trial exists only when a reasonable jury could find for the party opposing the motion based on the record as a whole.” Pipitone v. United States, 180 F.3d 859, 861 (7th Cir. 1999) (quotation marks omitted). “The ordinary standards for summary judgment remain unchanged on cross- motions for summary judgment . . . .” Blow v. Bijora, Inc., 855 F.3d 793, 797 (7th Cir. 2017). The court simply “construe[s] all inferences in favor of the party against whom the motion under consideration is made.” Metro. Life Ins. Co. v. Johnson, 297 F.3d 558, 561–62 (7th Cir. 2002) (quotation marks omitted).

“One of the principal purposes of the summary judgment rule is to isolate and dispose of factually unsupported claims or defenses . . . .” Celotex Corp. v. Catrett, 477 U.S. 317, 323–24 (1986).
