Recently, I've seen L2 projects arguing over TPS, fees, and subsidies, and it's making me a bit amused… No matter how fast the chain is, if you lose your keys, it's still zeroed out. To be honest, unless the asset size reaches a certain level, hardware wallets are sufficient; don't overcomplicate things. When it gets to the point of "not being able to sleep," multi-signature is more secure, but daily operations become more troublesome, and you have to accept that transfers are like following a process. I think social recovery is suitable for people who are afraid of losing their mnemonic phrases and don't want to bother with complicated procedures, but only if you trust those few "recovery persons," otherwise you're just shifting the risk elsewhere. Anyway, my current approach is: keep large amounts cold, run strategies with small hot wallets, and tonight I'll revoke the authorizations of a few old DApps before going to sleep.
