That’s why play and test with small amount. Repeat until comfortable
Discussion
I suppose I'll have to take the plunge at some point. Multi vendor, multi sig, is the way to go for the ultimate in security.
Been going through this discussion a lot with a few friends. From technical security perspective, I agree and want to try and play around with. But I keep coming back to fiat world mentality in a way. The government bullshits people that deposits are safe to a certain amount so people naturally open multiple bank accounts. Key safety targeted with multi sig, multi device but I think maybe worth considering multi device / seeds division. Stack on a wallet to certain amount and hide and start another. I have never had only one bank account
You're right. I currently have all my stack on one device. I recently received 2 Jades so the least I can do is split it between the 2 of them. (I've still not done it because I'm lazy😂), I have 4 bank accounts, the total amount in all 4 is less than 4 figures😬.
I think it’s partially what comes naturally. As someone who worked internationally all his life and also got paid in different currencies and have always had to manage currency fluctuation risks, I’ve always had multiple accounts with multiple institutions in multiple countries and had to juggle things. When FATCA and CRS happened, had to juggle further just cause many banks couldn’t deal with the bloody regs and told me to shut accounts. It just became normalised. It seems normal for me to have multiple devices and wallets in different locations using different devices
complex 25th word on your standard seed does a damn good job. I’ve seen people post their seed phrases online as a challenge but because their 25th word was too complex for a brute force crack nobody ever got the money. Another option is single vendor, single seed multisig wallet created by using the same seed/HW but different 25th words on each key you add to the multisig setup using your HW
That’s a good option. Like it.
similar idea but instead of passphrases, using BIP85 child seeds to construct a multisig wallet using a single hardware device
zero transaction history at the master seed and child seed levels (suggests zero usage for anyone who might discover)
optional passphrase on "child seed 2" to add more "what you know" in recreating the wallet descriptor (think 3rd xpub)
backup requirements are 12/24 words, index of child seeds (out of 10,000) and optional passphrase, if used
note: not a recommendation, more of a thought exercise to poke holes
Neat ideas folks.
