### What Are Mt. Gox Repayments?
Mt. Gox repayments refer to the ongoing process of distributing recovered Bitcoin and Bitcoin Cash to creditors of the defunct exchange that filed for bankruptcy in 2014. This initiative is managed by rehabilitation trustee Nobuaki Kobayashi and officially began in July 2024, following years of legal and logistical preparations to ensure compliance and security.
To date, approximately 19,500 creditors have received partial refunds. However, the full repayment process has been extended to conclude by **October 31, 2026**, due to procedural challenges involving verification, regulatory compliance, and coordination with various exchanges.

### How Did the Mt. Gox Hack Occur?
The Mt. Gox hack exploited a vulnerability known as **transaction malleability**, which allowed attackers to alter transaction IDs undetected for years. This exploit enabled hackers to siphon off 850,000 BTC—nearly 7% of the total Bitcoin supply at the time.
The breach remained unnoticed until early 2014 and resulted in losses valued at $475 million then—but this is equivalent to over $97 billion today, based on Bitcoin prices around $100,000 per coin.
According to reports from the U.S. Department of Justice, two Russian nationals were charged in 2023 with laundering 647,000 BTC stolen in a 2011 incident linked to the hack. This investigation also led to the recovery of 140,000 BTC, currently worth about $16 billion.
Mt. Gox’s former CEO, Mark Karpeles, has emphasized the importance of cautious investment. Meanwhile, regulatory pressures compounded the exchange’s difficulties; the U.S. Department of Homeland Security seized $5 million in funds for Mt. Gox’s failure to register as a money transmitter.
Bankruptcy filings revealed liabilities of $64 million against $38 million in assets, affecting 127,000 creditors—most of whom were located outside Japan. Trustee Nobuaki Kobayashi has continued efforts to recover damages and pursue justice, as noted in official rehabilitation updates.

### Frequently Asked Questions
**What caused Mt. Gox to go bankrupt in 2014?**
Mt. Gox’s bankruptcy was caused by a massive hack that drained 850,000 BTC through transaction malleability, combined with increasing regulatory scrutiny from U.S. authorities and a lawsuit from partner CoinLab. The exchange suspended operations in February 2014 and subsequently filed for bankruptcy in Tokyo, revealing insolvency due to debts exceeding assets and prioritizing creditor protection under Japanese law.
**When will Mt. Gox creditors receive full repayments?**
Full repayments are now expected to conclude by **October 31, 2026**, following extensions from the original 2024 deadline. Delays are attributed to the need for verifying creditor details, ensuring compliance with regulations across different jurisdictions, and coordinating secure distributions of Bitcoin and Bitcoin Cash with exchanges.
