10 HWWs is 10 points of failure in my eyes. Not the worst plan though!

With a 2 of 3 multisig you can spend on your own BUT if you fuck up and lose access to one of your signing devices aka hardware wallets a trusted third party could sign a transaction with you.

I genuinely need to YT how this whole mulsig situation actually works - I’m not 100% sure..

Do you think it’s good to swop HWW every 1-2 years just for good security?

Collaborative 2 of 3 multi sig is elite AF in my books. I find it to be the perfect balance of security trade offs for many people. Definitely worth digging into :)

If your private key never touches the internet / your hardware wallet has never been plugged into the USB port of an internet connected mobile phone or computer and your seed-phrase backups haven’t been compromised I don’t see any reason to upgrade hardware devices every 1-2 years.

Unless: you are having issues with your current hardware wallet, the hardware wallet company has had security issues or data breaches or the device you want to get is a significant improvement on what you have.

Interesting - so Trezor is no good?

ColdCard MK4 is still the pick of the litter 100%

Foundation devices Passport / Blockstream Jade Plus are both solid choices

Trezors that are Bitcoin only aren’t terrible choices but I would be going for a ColdCard still.
