It depends on what you need it to survive. Foundation (Passport) runs hardware wallet custody, with no single point of failure recorded: no one institution's failure reaches your bitcoin on its own. Proof of Custody scores it 81/100 as of 2026-08-03. Single-signature hardware wallet is a good fit for learning self-custody with amounts you can afford to lose while you learn, and the wrong choice for life savings: one firmware defect, one coerced evening, or one lost seed is total loss — one failure domain is the whole story. The score is an editorial judgement; the facts to check are the custody model, the single point of failure and the incident history below.
