Gotta have an Inheritance plan
Go with Nunchuck Honey Badger plan
You get the benefits of collaborative custody, inheritance planning, mobile & desktop support, and you can manage the wallet with Sparrow if you prefer that interface
what is benefit to Numchuk vs say Unchained or River
Great guide, thank you. Been using Sparrow + Coldcard on my own node and was primarily curious about Single Sig vs. Multi Sig after watching an old Andreas Antonopoulos clip where he was saying Multi Sig is risky for non-technical users because if even1 xpub is lost then the wallet is gone forever even with the private keys. I believe that's what he was trying to say at least, I may have misunderstood.
yea, that was a while ago, saving redundant copies of the sparrow wallet file mitigates that, or redundant copies of the xpubs
