Contract authorization is really like sleeping: you can survive without doing it, but eventually something will go wrong. Many people click "Approve Unlimited" once and act like nothing happened, but in reality, they are just lending the keys to the tokens in their wallet, without setting a return date. Even the most reputable project can't prevent front-end hijacking, contract upgrade pitfalls, or you accidentally clicking on a phishing link someday... At that point, it's not "being hacked," it's you signing it yourself.

Recently, the community has been arguing about the compliance boundaries of privacy coins/mixing, and I just want to laugh: the most common "theft" on-chain doesn't even require mixing; just taking advantage of that one set of permissions you forgot to revoke is enough. To put it simply, revoke permissions after use—don't find it troublesome; I now make it a habit to check my authorization list before bed, or I always feel like I forgot to turn off the lights somewhere. Some people still think unlimited approval saves gas, but I can only say, saving that little bit isn't worth the peace of mind.
