ConstrainedCase description
A Bitcoin miner who died in April 2020 from COVID-19 had accumulated coins since 2011. The estate found six old computers. Blockchain forensics linked three to addresses with significant historical balances. Only one wallet was recoverable — the others had been encrypted with unknown passphrases. The estate recovered approximately 30% of the estimated total holdings.

What this illustrates
There was only one way in. When that path was gone, so was access. 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.
