Survives
Case description
A user who had purchased Bitcoin in 2017 and stored it in an Electrum wallet attempted to move funds to a hardware wallet in June 2022 following the Celsius collapse. On reopening the Electrum wallet after several years of inactivity, the user could not remember the wallet password. The user retained the wallet.dat file. Recovery was eventually achieved using btcrecover with a custom wordlist based on the user's known password patterns from 2017, after approximately three weeks of GPU computation.
