Oh yeah, I also like multisig for inheritance.
Do you have any suggestions on good ways to do inheritance planning with single sig where you still have control over your funds while you're alive but your heir gets control once you pass?
Discussion
There are several services for this. If you want to roll your own then tell your loved ones where the seed backup is hidden. Then have a Deadman email set up with your passphrase.
Thanks, I'll look into that.
Related to my prior response on the 4 attacks multisig may help combat, do you have any thoughts?
Also, is there a given dollar threshold at which you think it may be worth 'upgrading' to multisig even for an anon holder? Like say some guy has a 100k, 500k, 1 million dollars? At some point does the added complexity become worth the effort for (even if only slightly) better security?
There is no way I can answer that. There are just too many variables and it is going to depend on the person and their situation.
$1,000 is a fortune to some people while others spend $500k on a fun night in Vegas.
Perhaps it would be better if I rephrase.
If you are securing what to you is a fortune (however you define it), would you opt for the additional security (& complexity) of multisig, or as a non-public bitcoiner, would you feel comfortable with single sig + passphrase?
A single sig is plenty secure. Satoshi has a single sig and no one has hacked him.
Multi sig is intended to protect you if you lose one of the keys. For some people and certain situations that is good and they should use it. But multi sig increases the complexity. Most people are better off with one seed with multiple physical copies in different locations.
If you are air gapped your possibility of being hacked remotely is basically zero. The threat then becomes physical. Single sig + passphrase makes a two part secret. Don't keep them together for the evil maid.
Don't become a target by connecting your name and location to a stack. Have multiple wallets and UTXO's, obscure how much you have.
