Recently, I saw a bunch of new L1/L2 projects promoting incentives to boost TVL, and old users were complaining "mining and selling"... I actually worry more about another small issue: you just want to claim some tokens or swap to another coin, so you casually give the contract an "unlimited approval," and then forget about it.

To put it simply, it's like lending out your house keys without getting them back; you don't notice it normally, but if something goes wrong, you wake up one day to find your balance significantly reduced. Revoking permissions is as important as sleeping: you can live without doing it, but doing it gives you peace of mind. My current habit is to revoke permissions after use, even if it's a two-minute hassle, to avoid suspicion and paranoia every day later. Anyway, I’d rather miss out on a bit of efficiency than gamble with luck.
