Airdrop season is getting more competitive, almost like going to work every day, and the task platforms are still full of anti-witchcraft measures. I'm now more concerned about "how to prevent assets gained from interactions from being lost in one wave." To put it simply, it depends on the amount: within a few thousand dollars, a hardware wallet is enough—peace of mind; once it reaches five figures, I want to use multi-signature, even if it's more troublesome, at least I won't lose everything with a shaky hand; when it reaches the level of "must not lose," social recovery is suitable for those who can't remember seed phrases and are afraid of losing hardware, but only if you trust those contacts, or else the psychological pressure becomes even greater.
