Recently, I've seen a bunch of narratives about AI agents doing automatic trading and on-chain interactions flying around. To be honest, the more "automatic" it is, the more you need to think through authorization and keys first; otherwise, you're just extending your hand to let someone pull the trigger...

Hardware wallets are suitable for assets where "I'd rather be a bit more trouble but more secure": large amounts stored long-term, signing with a button, avoiding messy dApps. Multi-signature is more like a team/family ledger; the money can't be moved on a whim by one person, offering high fault tolerance, but setting up and maintaining it really tests patience. Social recovery I think is suitable for the middle ground: you don't want to operate hardware every time, but you're afraid of losing your seed phrase and resetting everything, so you reduce the chance of "losing everything" — but only if your guardians/mechanisms aren't chosen too hastily.

Anyway, choosing which option isn't fate; it's about selecting the probability of different troubles/risks that you can bear. My usual approach is: keep long-term holdings cold and interactions hot, and don't put everything in one basket.
