How scoring works →Summary
Mt. Gox was a Tokyo-based Bitcoin exchange that, at its peak in 2013–2014, handled approximately 70% of all global Bitcoin transactions. In February 2014 it suspended trading and filed for bankruptcy after disclosing the loss of approximately 850,000 BTC — later revised to approximately 650,000 BTC net — due to theft that investigators determined began as early as late 2011. Creditor repayment proceedings under civil rehabilitation law have been ongoing since 2018, with partial distributions commencing in July 2024 and a current deadline of October 31, 2026.
