In the world of cryptocurrency, Mt. Gox stands as a cautionary tale. Following its bankruptcy proceedings initiated in 2014, many creditors are still seeking restitution after the immense loss of over 850,000 Bitcoin (BTC). Originally scheduled for repayment by October 31, 2025, the deadline for these repayments has been pushed to October 31, 2026.
Updates from the Trustee
The rehabilitation trustee, Nobuaki Kobayashi, shared a recent update indicating that most repayment processes—including the Base Repayment and Early Lump-Sum Repayment—are close to completion for creditors who have met all necessary requirements.

So far, those who followed the required protocols have successfully received their payments.
However, a significant number of creditors remain unpaid due to “incomplete procedures or various undetermined complications” amidst the repayment efforts. These challenges were not elaborated upon in the trustee’s statements.
To navigate these repayment complexities, the Mt. Gox trustee has attained court permission to extend the repayment deadline to October 31, 2026.
The Journey of Mt. Gox
Once at the forefront of cryptocurrency exchanges, Mt. Gox dominated the market with a staggering share of Bitcoin trading volume, accounting for between 70% to 80%. This dominance, however, made it an appealing target for cybercriminals, leading to a series of security breaches.
In 2011, a vulnerability stemming from stolen login credentials enabled hackers to siphon off thousands of Bitcoin. Compounding the issue, deficiencies in network protocols led to further losses that year.
As 2014 dawned, users began to express growing frustration over dwindling access to their funds. Technical malfunctions made it difficult for customers to verify transaction statuses, prompting concerns about their Bitcoin transferability.
This was linked to a flaw in Bitcoin’s software, referred to as “transaction malleability,” which allowed users to manipulate transaction IDs. While this explanation has received some skepticism in the crypto community, a settlement was reached to mitigate the fallout.
Challenges Faced by Creditors
The situation reached a critical juncture in February 2014, when Mt. Gox halted withdrawals due to suspicious activity detected in its digital assets, ultimately disclosing that a substantial amount of Bitcoin was missing. Total loss estimates fluctuated between 650,000 and 850,000 BTC.
The trustee, Nobuaki Kobayashi, has extended the deadline for submitting claims multiple times—five extensions between October 2019 and October 2020 alone. In November 2021, he publicized a rehabilitation plan that earned approval from both Japanese courts and creditors.
Despite these efforts, many have voiced dissatisfaction over the lack of transparency regarding the rationale for prolonged deadlines. As a result, creditors now face yet another year of uncertainty for potential repayments, which may occur at values significantly lower than today’s market prices.
Currently, Bitcoin is trading at $114,813, reflecting gains of 2% and 3.5% in the 24-hour and weekly periods, respectively. Remarkably, this price positions Bitcoin merely 8.8% shy of its all-time high of $126,000.
