Institutional custody dependency — exchange — Japan 2022
IndeterminateCase description
After the September 2022 Mt. Gox claim registration deadline passed, the trustee still could not set a repayment date, stating it would be determined 'in due course.' Creditors who had been waiting since the exchange's 2014 collapse faced continued indefinite delay. The repayment deadline itself had already been extended multiple times throughout 2022, requiring creditors to repeatedly re-engage with a complex legal process in a language and jurisdiction unfamiliar to most non-Japanese claimants.
