Never trust a hardware wallet. They can fail at any time or get lost or stolen.

I imagine there’s a way of backing it up as well, that covers you from both angles. If your online wallet goes bye bye, you have the hardware wallet to restore it. If the hardware wallet fails, you have a copy backed up online. I.haven’t read everything about it, but their website probably has some form of a “vault” to keep your backup in. Or you could keep a copy in your own backup spot or both.
Better to have and not need, than to need and not have.😁
two of them
That’s not a bad idea either, but then you have to make sure they’re both backed up at the same time. I’m just starting so it’s a ways off for me. I’ll grab one(or two) when I have a more substantial amount of sats to protect. Right now I am just testing the market to see how it works and it doesn’t look like bitcoin is any different from any other commodity being traded. That at least makes that part easier.
