Hardware wallets, multi-signature, social recovery — these three I currently understand quite roughly: if you have little money and lose it, it’s not a big deal and you won’t lose sleep, so don’t turn yourself into an operations engineer; if you have a lot of money and “even one wrong transfer hurts,” then hardware wallets come first, at least to block daily slips. Further up, when assets start to be dispersed, and you need to frequently operate across chains/DeFi, multi-signature makes more sense — otherwise, a single private key is both a ticket and a noose. I’m quite conflicted about social recovery; it sounds gentle, but you first need to confirm whether “friends” are another knife, because changing relationships can be more troublesome than hackers.

By the way, retail investors complaining daily about unfair validator/MEV ordering isn’t without reason; in short, on-chain queuing can be front-run, so don’t expect “convenient” signature methods to be foolproof and safe. Anyway, I now keep the main assets cold and have a small hot wallet for itching, don’t gamble with yourself.
