Hidden wallet discovered — hardware wallet (2022)

Indeterminate

Case description

A case highlighted in 2022 estate planning guidance involved a Bitcoin holder who suffered a sudden stroke and was left in a long-term care facility with severely impaired cognitive function. The holder's family held a general power of attorney but discovered it did not grant the ability to access a hardware wallet: the POA allowed them to act on behalf of the holder in financial matters, but the Bitcoin required the holder's personal passphrase and PIN. Without the specific technical credentials, the POA was legally valid but practically unusable.
