The best cold storage device in the #Bitcoin space is the Coldcard.
⚠️ BUT - the firmware is not open for extension or modification. It is not free, only source viewable.
This is sad. Free and open source software is not a "nice to have", it is the lifeblood of #Bitcoin.
Doesn't that automatically stop it from being the best?
Why not seedsigner?
On balance, yes.
Both SeedSigner and Passport are viable alternatives for the idealogically inclined.
Great hardware devices.
The best cold storage is a seed phrase on steel in a safe.
Don't forget the 25th word, fren.
I love my steel plate
I love my cold cards
I love my seed signer
Maybe I have a problem but they're all fun and optimize for different things
Me too, man. Me too.
Bitbox02 (bitcoin only edition) is excellent - and open source, worth a look if you're in the market for self-custody (which you should be!) https://shiftcrypto.shop/en/products/bitbox02-bitcoin-only-4/
