Two wallet backups in two places do not automatically provide two independent recovery routes. Both may depend on one phone, fail in the same event or expose more information than intended. Review the events your plan can survive and what each location reveals if someone else gains access.
In a simple two-of-three multisignature wallet, spending requires accepted signatures from two of three independent keys. Losing one key may leave a spending route through the other two, provided the necessary wallet information and compatible tools remain available. Three copies of one recovery phrase are a different arrangement.
A used hardware wallet may power on normally without establishing who knows its existing keys or whether its history is trustworthy. Evaluate hardware integrity, official software and backup secrecy separately. A discount, clean box or working screen does not settle all three questions.
An address that resembles one you used before is not necessarily the same destination. Its middle characters may differ, the network may be wrong, or the source may be a misleading transaction entry. Verify the address source, complete value and receiving requirements separately before sending.
A USB drive stores files. A hardware wallet manages keys and signs requests through a dedicated design. Either may have a role in a custody plan, but a similar size or connector does not make them interchangeable. Follow the key through a complete transaction before comparing the products.
