Gox rehabilitation trustee Nobuaki Kobayashi extended the creditor repayment deadline
IndeterminateCase description
In September 2023, Mt. Gox rehabilitation trustee Nobuaki Kobayashi extended the creditor repayment deadline from 31 October 2023 to 31 October 2024, citing delays in verifying creditor information and coordinating with exchanges. This was the first major deferral since the court-approved rehabilitation plan was set in 2021. Creditors who had been waiting since the 2014 collapse—many for nearly a decade—were told again to wait, with no individual repayment timeline provided.
