Opinion

UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS EASTERN DIVISION

GREGORY GREENE, ) ) Plaintiff, ) 14 C 1437 ) vs. ) Judge Gary Feinerman ) MARK KARPELES, ) ) Defendant. )

MEMORANDUM OPINION AND ORDER The court’s prior opinions, familiarity with which is assumed, summarize the history of this suit, which concerns the collapse of the Mt. Gox bitcoin exchange. Docs. 199-200 (reported at 169 F. Supp. 3d 855 (N.D. Ill. 2016)); Docs. 229-230 (reported at 206 F. Supp. 3d 1362 (N.D. Ill. 2016)); Docs. 311-312 (reported at 289 F. Supp. 3d 870 (N.D. Ill. 2017)); Docs. 373-374 (reported at 327 F.R.D. 190 (N.D. Ill. 2018)); Docs. 409-411 (reported at 2019 WL 1125796 (N.D. Ill. Mar. 12, 2019)). As matters now stand, Gregory Greene, the sole remaining plaintiff, seeks on behalf of a putative class to hold Mark Karpeles, Mt. Gox’s principal and the sole remaining defendant, liable under a fraud theory for financial losses allegedly arising from Mt. Gox’s collapse. Docs. 245, 464. Karpeles moves for summary judgment, Doc. 452, and to strike the expert disclosure of Professor Carol Goforth, Doc. 457. The motions are denied. Background The court recites the material facts as favorably to Greene as the record and Local Rule 56.1 permit. See Johnson v. Advocate Health & Hosps. Corp., 892 F.3d 887, 893 (7th Cir. 2018). At this juncture, the court must assume the truth of those facts, but does not vouch for them. See Gates v. Bd. of Educ. of Chi., 916 F.3d 631, 633 (7th Cir. 2019). A. Karpeles, Mt. Gox, Hacks, and the Gox Bot Karpeles is the sole shareholder and CEO of Tibanne KK. Doc. 466 at p. 2, ¶ 4. In early 2011, Tibanne KK acquired 88% of the shares of Mt. Gox KK from Jed McCaleb, who maintained a 12% interest. Id. at p. 3, ¶ 7. Karpeles was the CEO of Mt. Gox KK from 2011 to

2014. Id. at p. 2, ¶ 5. The Mt. Gox bitcoin exchange was located in Japan and operated from 2009 to 2014. Id. at p. 2, ¶ 6. Users could create a Mt. Gox account and use it to buy, sell, and store bitcoins and fiat currency. Id. at p. 3, ¶ 8. Users also could transfer bitcoins or withdraw cash, and those transactions were processed through one of Mt. Gox’s banking partners—though Greene submits that users could not do so in practice or securely. Id. at pp. 3-4, ¶¶ 8-10. Beginning in 2012, Mt. Gox required that its United States users read and agree to its Terms of Use. Doc. 476 at ¶ 1. Karpeles directed the drafting and dissemination of the Terms, and he knew of their contents. Id. at ¶ 2. (Karpeles disputes this assertion, ibid., but his deposition testimony gives rise to a reasonable inference that the assertion is correct, Doc. 476-2

at 14-15 (96:8-97:18).) The Terms stated that Mt. Gox would maintain the buyer and seller anonymity and that offers could not be withdrawn once a price was agreed upon. Doc. 476 at ¶¶ 3-4. The Terms also stated that Mt. Gox members “agree that, when completing Transactions, they are trading with other Members,” and that Mt. Gox could be used to “buy and sell” bitcoins and “allows all registered users of the Platform (‘Members’) to transfer funds and Bitcoins to other Members and to use Bitcoins for purchasing specific items.” Id. at ¶ 5 (quoting Doc. 476- 1). The Terms required members to warrant that currencies deposited to buy bitcoins “are actual currencies corresponding to actual assets in [the member’s] bank account and coming from legal sources” and that “Bitcoins offered to sell or to transfer correspond to actual Bitcoins.” Id. at ¶ 6 (quoting Doc. 476-1 at 4). Mt. Gox promised in the Terms to “hold all monetary sums and all Bitcoins deposited by each Member in its Account, in that Member’s name as registered in their Account details, and on such Member’s behalf,” and to “use all reasonable care and skill” in facilitating bitcoin trades. Id. at ¶¶ 7-8 (quoting Doc. 476-1 at 4). Accounts that violated the

Terms were subject to suspension. Id. at ¶ 9. In January 2011, $50,000 was stolen from a Mt. Gox account. Id. at ¶ 10. Karpeles was aware of the theft and expressed concern about it, but he did not disclose it to Mt. Gox users. Id. at ¶¶ 11-12. In March 2011, an individual or individuals gained unauthorized access to Mt. Gox and stole 80,000 to 90,000 bitcoins. Id. at ¶ 13. From that point on, Karpeles was not sure that Mt. Gox would be able to satisfy its users’ withdrawal requests. Id. at ¶ 14. Karpeles believed it was important for users of a bitcoin exchange to know that the exchange was short bitcoins, but he was concerned that if the hack were disclosed, Mt. Gox likely would fail because disclosing it would lead to users demanding return of their bitcoins, which Mt. Gox could not do. Id. at ¶¶ 15-17. Karpeles believed that such a situation would negatively affect Mt. Gox and Tibanne

and present a difficult situation for him as Tibanne’s sole owner. Id. at ¶ 18. Karpeles did not disclose the March 2011 hack. Id. at ¶ 19. In June 2011, there was another hack of Mt. Gox, which caused the price of bitcoin to plummet and additional bitcoins to be lost. Id. at ¶ 20. McCaleb asked, and Karpeles agreed, to have McCaleb make “PR posts” on the bitcoin forum. Id. at ¶ 21. Mt. Gox experienced other hacks resulting in the loss of bitcoins. Id. at ¶ 22. Karpeles did not disclose to Mt. Gox users the full extent of the hacks. Id. at ¶ 23. Before Karpeles purchased (through Tibanne) a majority interest in Mt. Gox, McCaleb used a script—referred to as “Gox Bot”—to automatically conduct trades using commissions collected by Mt. Gox from user trades. Id. at ¶ 26. The Gox Bot continued trading after Karpeles acquired his interest in Mt. Gox, but he wanted to use the user trade commissions to recover the bitcoin deficit caused by the hacks. Id. at ¶¶ 27, 31. Some time in 2011, Karpeles disabled the feature that automatically credited Mt. Gox commissions to the Gox Bot account,

and instead began manually crediting the account as a “debt for Mt. Gox” and using the credited funds to execute trades. Id. at ¶¶ 28-30. McCaleb had asked Karpeles to keep the Gox Bot secret, and Karpeles never disclosed its existence to Mt. Gox employees or users. Id. at ¶¶ 31-32. Karpeles believes that the Gox Bot’s trading had only a minimal effect on bitcoin prices, but Greene cites Professor Goforth’s declaration for the proposition that the trading significantly impacted bitcoin prices. Id. at ¶ 34. Karpeles was convicted in Japan of data manipulation due to conduct relating to the Gox Bot. Id. at ¶ 35. On February 7, 2014, Mt. Gox suspended all bitcoin withdrawals. Doc. 466 at p. 8, ¶ 18. On February 24, 2014, the Mt. Gox website went offline. Id. at p. 8, ¶ 19.

B. Greene’s Mt. Gox Account and Interactions with Mt. Gox Greene obtained a Mt. Gox account in early 2012. Doc. 466 at p. 8, ¶ 20; Doc. 476 at ¶ 36. He purchased bitcoin and moved it onto the Mt. Gox exchange. Doc. 466 at p. 8, ¶ 20. Before he obtained his account, Greene had read an article that mentioned a 2011 Mt. Gox hack, but the article did not affect his decision to purchase bitcoin. Id. at p. 8, ¶ 21. Greene bought bitcoin twice, in January 2012 and March 2013. Id. at p. 9, ¶ 22. He knows that no website or bitcoin exchange, including Mt. Gox, is completely secure. Id. at p. 11, ¶ 28. Greene read the Terms of Use when joining Mt. Gox. Doc. 476 at ¶ 36. (Karpeles disputes this fact, asserting that the Terms were not posted until after Greene created his account. Ibid. But Greene testified that he read the Terms when he created an account, Doc.
