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. 

 If you are asking about potential problems with multisig you are probably going to have them. NVK (Coldcard creater) talks about this. You are much better off creating a Passphrase and keeping it separate from your Seedphrase. This is much safer for average users & if someone has your 24 words they won't be able to access or even see your bitcoin without the Passphrase I store my seedphrase on paper and a metal plate (lots of options available I bought mine from Coinkite) & my Passphrase is digital (& in my head!)
