But, with the tapsigner you don’t have to use multi-sig. You can simple do single sig.
I don’t quite understand what you mean. I suppose you mean using a multisig with a coldcard and a tapsigner? I would never use tapsigner for my main multi sig. I totally loose stuff on the regular and would be relying heavily on the back up of that one. And what I dread is loosing one of the wallets on the multi sig
