That's what I was going to recommend--why waste money on a HW wallet just to store bitcoin? Assuming you're going to keep it long-term, it would be so much cheaper and probably more convenient to transfer your bitcoin to an Electrum wallet, write down or stamp the seed phrase into a piece of metal and keep it in a safe place. You'd have to basically do the same thing with a HW wallet anyway, right?
This
could be a great idea, assuming that the user actually knows how to generate a wallet safely in an air-gapped manner(which is like a
very small minority of bitcoiners). But since OP is asking which hardware wallet to use, what are the chances? Just paying the $70 for a reputable hardware wallet is the way to go in 99.9% of cases.
