Case description

A Bitcoin early adopter who died in 2015 had created a wallet in 2010 and used it regularly until 2013. Since then the wallet had been dormant. The estate attorney found a reference to 'wallet backup 2010' on a USB drive but the file was corrupted. A data recovery specialist partially recovered the file but determined the wallet was password-protected with an unrecoverable passphrase.
