Hardware wallet risk isn't just about hacks—it's about hardware failure.
Real case: Trezor multi-sig setup bricked after a firmware update. Device wouldn't sign transactions anymore. Only the backed-up seed phrase saved the funds.
Ledger has a different failure vector: OLED screens on old Nano models degrade over time. Faded screen = can't enter PIN = device lockout.
Neither of these are security breaches. The hardware just stops functioning.
Practical takeaways:
• Old Trezor/Ledger models are ticking time bombs
• Firmware updates can introduce incompatibilities
• Seed phrase backup is non-negotiable—store it separately
• Multi-sig adds a recovery layer if one device fails
• Hardware degradation (screens, chips, connectors) is a real threat
Your $BTC isn't safe just because it's in cold storage. It's safe because you can recover it when the device inevitably fails.
