Mt Gox, the Tokyo-based exchange that had handled most of the world’s bitcoin trading, filed for bankruptcy protection in the Tokyo District Court. Chief executive Mark Karpelès said around 850,000 bitcoins had been lost, blaming weaknesses in its systems.
What happened
- Mt Gox suspended withdrawals in early February 2014, citing technical problems, and went offline later in the month.
- About 750,000 of the missing bitcoins belonged to customers and around 100,000 to the company, worth roughly 470 million US dollars at the time.
- The exchange reported debts of around 63.6 million US dollars.
- Mt Gox later said it had found around 200,000 bitcoins in an old wallet.
Why it mattered
The collapse was the biggest failure in cryptocurrency’s early history, wiping out customer funds and prompting calls for regulation of exchanges. Creditor repayments only began in 2024.
Lessons for organisations
Organisations holding digital assets need strong key management, segregation of client funds, independent audits, and reconciliation controls. Anyone relying on a third-party custodian should assess its security and financial resilience as part of supplier due diligence.
