I'm personally mostly using the
Passport Batch 2. Definitely recommend against just using a USB flash drive. They typically have no security measures and are not made for long-term storage. And whatever you do, create a few seed phrase backups. A cheap and long-term secure way to do that is using
steel washers.
Youch, I have under 550 dollars of btc and I want a cheap way to store my btc is there any cheap hardware wallets u recommend?
Do keep in mind that is $550 now can easily be $1,000 or more in the future. Make sure your storage solution is also suited in a longer term, not just for this moment in time.
The cheapest recommendable hardware wallet is probably still the original
Trezor Model One. Do keep in mind that it comes at the cost of being susceptible to hardware attacks, so make sure nobody gets access to it.
