An early Bitcoin adopter died from COVID-19 in March 2020.
ConstrainedCase description
An early Bitcoin adopter died from COVID-19 in March 2020. The estate found nine paper wallets of varying ages. Six were empty (funds spent years earlier). Two had small residual balances. One had a significant balance but the private key portion had been obscured with black marker, apparently as a security measure. The obscured portion could not be recovered.

Structural dependencies observed
What this illustrates
No backup path existed. One point of failure was all it took. 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.
