1500 BTC?? I would set up a multi sig vault using a collaborative custody with 2 hardware wallets / signing devices.
Discussion
So you wouldn’t have 10x HWW geographically located around the world with 150BTC in each HWW?
Multisig - if I wanted to spend I’d need you and me to be online at the same time right?
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.
