In 2014, a major security breach at Mt. Gox resulted in the loss of 850,000 Bitcoins, leaving investors in a decade-long struggle to recover their funds.
Over the years, Mt. Gox repeatedly postponed its plans to reimburse users for funds that had been locked since February 25, 2014. This delay stretched the wait into its 11th year. The breach, followed by leaked documents indicating insolvency, eroded trust in the exchange.
Leaked documents revealed that "cold storage" had been depleted due to leaks from "hot wallets," raising concerns about the company's financial stability. This situation led some to argue that bankruptcy was a deserved outcome.
At that time, Mt. Gox managed 70% of all circulating Bitcoins, causing anxiety that its collapse might spell doom for Bitcoin itself. Consequently, the exchange filed for bankruptcy protection with the Tokyo District Court in Japan after losing nearly $500,000 in value.
Mounting lawsuits added to the legal complications surrounding Mt. Gox, and suspicions grew as the exchange removed its website and social media presence without communicating any compensation plans. CEO Mark Karpelès faced arrest on suspicions of manipulating computer systems but was later released without charges. The lack of cryptocurrency regulations poses challenges for authorities in prosecuting cryptocurrency-related crimes.
On April 22, 2015, Mt. Gox's bankruptcy trustee, Nobuaki Kobayashi, instructed users to file claims for their lost Bitcoins through either mail or a form accessible with their Mt. Gox login details.
Taking the falling Bitcoin market prices into account, Mt. Gox anticipated returning approximately 20% of users' funds. They disclosed an expectation to distribute only $91 million in assets to claimants. However, not all investors were content with this plan, resulting in total claims amounting to $2.4 trillion, far surpassing the actual losses of about $500,000.
During this period, the practice of storing cryptocurrencies in "cold wallets" gained significant attention within the cryptocurrency community. Karpelès faced legal action for alleged misappropriation of funds, including his involvement with the "Willy Bot," believed to manipulate exchange volumes during peak periods .
In November 2017, Karpelès proposed an initial coin offering (ICO) to raise $245 million for the revival of Mt. Gox. However, legal obstacles led to the abandonment of the ICO plan.
Following a strong price recovery in 2017, Mt. Gox revised its policy in August 2018, suggesting that all of its assets should be distributed to creditors rather than shareholders. Despite ongoing discussions, a satisfactory solution that meets legal and creditor demands remained elusive.
Amid anticipation of Mt. Gox's recovery, the exchange sought extensions for the submission deadline of its rehabilitation plan. In October 2019, the Tokyo District Court granted an extension, moving the deadline to March 31, 2020.
In early 2020, Fortress, a New York-based private equity firm, offered to purchase Mt. Gox's creditor claims, potentially providing eligible creditors with $1,293 for each Bitcoin held in their exchange wallets.
Further delays arose when, in March, Mt. Gox released a draft recovery plan that included the liquidation of cryptocurrencies other than Bitcoin (BTC) and Bitcoin Cash (BCH). The Tokyo court granted another extension, citing the need for closer examination of certain matters.
The court's actions led to the postponement of the Mt. Gox Bitcoin settlement date to October 15, 2020, with subsequent extensions into the following year.
Finally, on October 20, 2021, Mt. Gox creditors approved a recovery plan with overwhelming support from about 99% of affected creditors. With Bitcoin reaching an all-time high of $69,000, there was optimism that Mt. Gox's holdings would suffice to cover all losses.
This optimism carried into 2022 as investors registered for repayment options, but concerns arose about the potential impact of releasing 150,000 BTC on the Bitcoin ecosystem. The deadline for creditor registration was extended twice in 2023, but on April 7, Mt. Gox trustee Kobayashi declared that the deadline for creditors to provide repayment details had passed.
To the disappointment of creditors, Mt. Gox shifted its repayment deadline to October 2024. As of now, Mt. Gox has not responded to inquiries about its commitment to repaying user funds. In a letter dated September 21, the trustee, with the Tokyo District Court's permission, extended the periods for basic repayment, early one-time repayment, and mid-term repayment.
