Coldcard is shit. Ledger is shit. The best way to preserve your bitcoin is to first understand that “bitcoin wallets” are pretty unnecessary. While I have them, they serve a different role and are not the best solution for long term storage. Get a seedsigner. nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl

What is a seedsigner?
How does it defer from other custody services?
Seedsigner generates a seed then all data is wiped when the device loses power when you unplug it. Coldcard holds the seed in the device.
ok, really mad_? tell us why seesigner is the best for LTS? u never explaind your point, r u paid commission by SSigner? the QR u generate is no safer than another seed on any surfaces? at least the buttons on ccard works, SSigner doesn't even have the rubber caps on the push buttons in barebone kit, how many ppl will be using products like that, only nerds like your dentist, product market fit not yet there for ssigner unless u tell us otherwise. peace mad_
I am ignorant. Is seedsigner not a hardware wallet just like coldcard. Only difference you build it from scratch?
Stateless so the device itself is "immune" to physical compromise.
Commodity hardware dramatically reduces the chance of supply chain attack.
Commodity hardware also reduces the chances of being identified as a target for having enough bitcoin to come after.
Seedsigner is not immune to physical compromise. By default it has no tamper evident properties. If you're depending on it as your sole hardware signing device, I would strongly encourage locking it up when not in use and using a tamper evident tape. Odds are low that you'll ever experience an issue, but no reason not to add extra low cost layers of defense.
Seedsigner doesn’t save the seed on the device. Once it loses power the seed is wiped. Coldcard stores the seed in the hardware
