Recently, I saw someone granting permissions on a contract and defaulting to an "unlimited" limit, basically like leaving the house keys in the hallway. Usually nothing happens, but once there's an issue, it’s terrifying. I used to be lazy too, thinking if I didn't click, I couldn't place an order... But I was really scared once by a phishing link. Since then, after placing an order, I habitually revoke the permissions, just like turning off the lights before bed—if I don’t do it, I feel uneasy.

Especially now, hardware wallets are out of stock, phishing is highly prevalent, and everyone's security awareness is suddenly on high alert. But I think the most likely to be overlooked are these old authorizations. Now I have a bit of OCD: I wait for confirmation, wait for a pullback, wait until I think clearly before opening a position. If I haven't thought it through, I won't give the contract an "unlimited" backdoor. If I lose money, I stop for a week—at least I can sleep well.
