Someone said, "I didn't put much money on the chain, so unlimited approval doesn't matter"... I used to think the same.

Later, after watching the mempool closely, I really feel that approval is like leaving the door unlocked; nothing happens normally, but when something goes wrong, it's a total disaster.
Honestly, if you give DEX/aggregators/various small tools unlimited limits, and their contracts are replaced with fake ones, the front end is phishing, or you click the wrong link, the funds can move faster than you can react, and there's no time to even review the slippage.

My current habit is: withdraw immediately after use, or at least clear out the unused approvals, like turning off the gas before bed—more trouble but peace of mind.
Recently, hardware wallets are out of stock, phishing links are everywhere, don't rely on "I'm very careful" to withstand it; sometimes, just a tired hand trembles.
Anyway, I prefer to revoke a few more times than wake up one day to find approvals still sitting there.
