Had a Ledger Nano X for 2 yrs. Really liked it, especially the interface; however the recent scares about a back door led me to swap to Coldcard + Sparrow + Umbrel. Coldcard has lots of interesting features.

Question for the pros: is multisig all it's cracked up to be in regard to safety? It seems like you are creating more vulnerabilities in terms of long-term loss of keys. Where do you store all these keys? In a bank vault? With friends? With a pirate's map? Seems like it's adding ways to make an error. If I die, ensuring my kids get my keys is increasingly hard when using multi-sig. With one key, it seems simpler. Obviously it's a personal choice. Just curious to hear everyone's thoughts. Maybe I've overlooked something.
