Creditors needed to have registered with the designated exchange partners, completed
ConstrainedCase description
A significant cohort of Mt. Gox creditors who had not maintained active contact with the rehabilitation process over the preceding decade faced practical obstacles to receiving repayment in 2024. Creditors needed to have registered with the designated exchange partners, completed KYC, and confirmed their account details. Those who had changed email addresses, moved countries, or whose legal identity had changed since the 2014 bankruptcy filing needed to submit additional documentation. Some creditors who had purchased Mt. Gox claims on the secondary market also faced delays in establishing their right to receive distributions.

What this illustrates
Getting access back required help from an institution — and that help wasn't available. Whether full access was ultimately possible is unclear, but significant delay or outside intervention was involved.
Outcome interpretation
Access remained possible, but only with delay, dependence, or significant difficulty.
