A Bitcoin holder died in December 2021 near the all-time high.
ConstrainedCase description
A Bitcoin holder died in December 2021 near the all-time high. The family knew about their Bitcoin holdings but not their value. A blockchain forensics firm identified 8 wallets. Seven were accessible. The eighth was a multisig wallet requiring signatures from two other individuals who had been business partners. One partner cooperated; the other had died the previous year.

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.
