These days, I’ve seen people watching large on-chain transfers and exchange hot and cold wallets, shouting "Smart money is coming/going" whenever there's movement. I find it a bit annoying… Honestly, first understand your own keys before analyzing what others’ wallets are doing.

Assets aren’t very large yet, mainly for daily interactions. I think a hardware wallet is enough—low cost, and at least you won’t be educated by browser plugins again; but when it’s a size where “losing it means sleepless nights,” multi-signature is more reassuring. The downside is also real: it’s troublesome, and the signing process can get lazy when it’s too long. Social recovery sounds very appealing, suitable for those who fear they can’t remember seed phrases, but you have to truly trust those “friends/devices,” otherwise you’re just shifting the risk from yourself to others.

Right now, I keep my hot wallet for petty cash, my hardware wallet for medium holdings, and multi-signature only for the long-term, inactive portion… I’ve thought about the exit path first—don’t wait until you see abnormal activity to start worrying. That’s it for now.
