If I securely reinstall a barebones linux distro, or run Tails, do you folks consider this airgapped, even if at some point this computer was online?
I'd say airgapping is more about future actions than about past actions: make sure the data on it can never reach the internet in the future (including accidentally plugging in an ethernet cable).
I trust an old laptop with wifi disabled or removed, far more than I trust a new laptop purchased online.
What do you consider "old"? Anything older than Bitcoin itself will lack processing power, anything a few years old won't be much different than anything you buy new now.
Alternatively, what is the consensus around using an old Coldcard with dice rolls? Still considered untrustworthy?
Why risk it? I wouldn't trust the damn thing to use it as a coin to flip in the air.
I'm personally leaning towards dice rolls, but not sure yet how to convert them to a seed
There's software for it, but I prefer the manual solution using the
BIP39 word list.
Let's use a coin, flip 1 times: 10011101001. That's binary. Make it decimal: 1257. From the list, your first seed word is "
other". The last word includes a checksum, that's a bit more tricky.
Binary from a dice:
1 > 01
2 > 10
3 > 11
4 > 00
5 > 0
6 > 1
When using any software, I'm always thinking: what if it doesn't use my own input, but instead just gives a predetermined seed? That's why I'm okay using the software, but only if I can manually verify it.
