In the early days of Bitcoin, Mt. Gox was by far the most prominent Bitcoin (BTC) exchange in the world. The Tokyo-based company was responsible for more than 70% of all Bitcoin transactions in 2013. However, by early 2014, it had collapsed spectacularly, leaving investors and traders with losses amounting to hundreds of millions of dollars.
The downfall of Mt. Gox was a defining moment in the history of Bitcoin and cryptocurrency in general, with several regulators, market analysts and industry experts continuing to study the case to prevent such instances in the future. Moreover, the saga has continued to serve as a cautionary tale for the cryptocurrency industry, highlighting the potential risks and pitfalls associated with digital currency trading and investments.
Mt. Gox: The early years
Mt. Gox was launched in 2010 by Jed McCaleb, a programmer and entrepreneur who had previously founded the file-sharing network eDonkey2000. At the time, Bitcoin was still a niche technology that was largely unknown outside of a small group of enthusiasts and developers. Mt. Gox was one of the first exchanges that allowed users to buy and sell Bitcoin for fiat assets, thereby quickly amassing a high degree of popularity among early adopters and traders.

In 2011, McCaleb sold Mt. Gox to Mark Karpeles, a French software developer who had previously worked on various projects, including an online marketplace called “Magic: The Gathering Online Exchange.” Karpeles moved the company’s headquarters to Tokyo and began to expand its operations, opening up new markets and adding support for additional cryptocurrencies. This transformed Mt. Gox into the most prominent crypto trading ecosystem of the early 2010s.
In February 2014, Mt. Gox abruptly halted all withdrawals from its platform, citing technical issues and security concerns. The company’s website went offline, and rumors circulated that the exchange had been hacked. A few days later, Karpeles held a press conference in Tokyo where he confirmed that Mt. Gox had indeed been hacked, and miscreants had stolen 850,000 Bitcoin — worth approximately $450 million at the time.
The Mt. Gox hack was one of the largest thefts in the history of Bitcoin and cryptocurrency, and it had a significant impact on the broader industry. The price of Bitcoin dropped sharply in the days following the announcement, with many investors and traders losing confidence in the security and reliability of digital currency exchanges.
Mt. Gox hack aftermath
In the months following the Mt. Gox hack, there was great uncertainty and confusion about what had happened to the stolen Bitcoin, and who was responsible for the theft. Karpeles initially claimed that the coins had been stolen due to a “bug” in Mt. Gox’s software, but experts and members of the Bitcoin community widely criticized this explanation.
In March 2014, Mt. Gox filed for bankruptcy protection in Japan, and Japanese authorities seized the company’s assets. Karpeles was eventually arrested and charged with embezzlement and fraud in connection with the exchange’s collapse, but he has consistently maintained his innocence, claiming that he was simply a victim of circumstances beyond his control.
The Mt. Gox bankruptcy proceedings were complicated and protracted, with multiple legal challenges and competing claims from creditors and investors. In 2018, a Japanese court ruled that Mt. Gox’s assets should be liquidated and distributed among its creditors — a process that is still ongoing.
How are the reimbursement proceedings going?
In 2018, after several years of legal battles and investigations, a Japanese court approved a plan to compensate the victims of the Mt. Gox hack. The plan, which a court-appointed trustee proposed, called for the creation of a trust to hold the remaining Bitcoin and distribute them to the creditors. The trustee, Nobuaki Kobayashi, was tasked with overseeing the distribution of the remaining funds.
The first step in the plan was to convert the remaining Bitcoin into cash. The trustee sold over 35,000 BTC and 34,000 Bitcoin Cash (BCH) on various cryptocurrency exchanges, raising over $400 million. This was a significant achievement, as it represented the largest sale of cryptocurrency by a single entity in history.
In March 2020, the trustee announced that a new system had been implemented to allow creditors to make claims for the remaining funds. Creditors were required to submit proof of their claim, including documentation such as bank statements, transaction records and identification documents. The deadline for submitting claims was set for October 2020, which was subsequently pushed back to December.
In December 2020, the trustee announced that it had received claims from 99.9% of the creditors. The total amount of claims submitted was approximately $16 billion, which was significantly higher than the remaining funds available for distribution. This presented a significant challenge for Kobayashi, as he had to determine how to distribute the remaining funds fairly.
In January 2021, the trustee submitted a draft rehabilitation plan to the court. The plan proposed that the remaining funds be distributed in Bitcoin rather than cash, as this would avoid the need to sell the remaining cryptocurrency and risk affecting the market. The plan also proposed that the creditors be given the option to receive reimbursement in Bitcoin or cash, with the conversion rate based on the market price at the time of distribution.
As expected, the proposed rehabilitation plan received mixed reactions from the creditors. Some creditors welcomed the plan, as it offered the possibility of a higher reimbursement if the price of Bitcoin increased. However, others were skeptical, as the value of Bitcoin is highly volatile and subject to significant fluctuations. Some creditors also expressed concerns about the potential tax implications of receiving reimbursement in Bitcoin.
During the first week of September 2022, Kobayashi announced that former Mt. Gox customers had until Sept. 15 to make or transfer a claim. This date was then pushed back to Jan. 10, 2023, with Kobayashi urging creditors to complete the necessary steps before the deadline.
Kobayashi informed creditors that those individuals who failed to do so would be unable to receive their funds quickly or would be required to supply several documents to the firm’s head office in Japan. Even then, they would only be able to receive payments in Japanese yen.
However, the deadline was moved to March 10, citing the “progress by rehabilitation creditors” in the selection and registration as a reason for the change. In fact, as part of a March 7 announcement, the trustee reiterated a January notice reminding creditors who had not registered for repayment that they had until March 10 to do so — two additional months as part of the rehabilitation plan proposed earlier.
Kobayashi did not provide a reason for the extension, which would allow individuals who suffered losses at Mt. Gox to select a repayment method and register their information in an online rehabilitation claim filing system.
Additionally, it bears mentioning that amid all these changes, Mt. Gox Investment Fund — the largest creditor of the defunct crypto exchange — opted for an early payout in Bitcoin rather than wait longer for a larger payment after a legal battle. The early payout meant creditors would receive approximately 90% of what was due. The bankruptcy trustee doesn’t have to sell tokens to acquire fiat funds for the payment since the creditor also chose to be paid in BTC.
Most recently, the timeline for filing claims and distribution of assets to Mt. Gox creditors seems to have been amended again. As per an official announcement, the deadline for filing claims has been extended by another month, from March 10 to April 6, 2023, allowing creditors to register their claims for an additional period. The distribution of assets has also been pushed back by another month, with the process now starting on Oct. 31 instead of Sept. 30.
The official statement released by the Mt. Gox trustee cited several reasons for the delay in the deadlines, including the progress made by rehabilitation creditors in terms of selection and registration. Creditors have multiple options for receiving payments, including a lump-sum payment, bank remittance, via a transfer service provider or a cryptocurrency exchange or custodian.
Lessons learned and looking ahead
One crucial lesson learned from the Mt. Gox collapse is the value of transparency and accountability. Many critics argued that the hack’s severity was partly due to the exchange’s opacity and secrecy regarding its operations. Nowadays, reputable cryptocurrency exchanges are relatively more transparent, with some frequently publishing audits and reports to reassure customers and investors.

Another lesson from the Mt. Gox failure was the need for better risk management and financial controls. In the early days of Bitcoin, many exchanges were run by tech enthusiasts and entrepreneurs with little to no experience in finance or risk management. Today, exchanges have more professional and experienced management teams implementing better financial controls and risk management practices.
Lastly, the Mt. Gox hack revealed the necessity for improved regulation and oversight of the cryptocurrency industry. Since the collapse, regulators worldwide have proposed new rules and regulations to protect investors and traders, including stricter Anti-Money Laundering and Know Your Customer requirements. While some may view these regulations as excessively restrictive, others believe they are necessary to prevent fraud and safeguard consumers.
The Mt. Gox incident continues to serve as a cautionary tale regarding digital assets’ potential risks and dangers, emphasizing the need for greater transparency, accountability and risk management.
