Recently, I saw someone again focusing on large on-chain transfers and abnormal movements in exchange hot and cold wallets, then firmly claiming "smart money is coming." Honestly, this kind of narrative looks exciting, but the most vulnerable part of your wallet is often not the market direction judgment, but those contract authorizations you casually clicked before.

Unlimited authorization is like giving your house key to a stranger and not taking it back: the project team may not be malicious, but if the contract is hacked / the front end is hijacked / you fall for a phishing scam, it’s all a matter of stepping on the gas pedal. Revoking permissions is as important as sleeping; you can survive a few days without doing it, but problems will eventually arise. Anyway, I now revoke permissions immediately after use, especially when authorizing unknown DApps, cross-chain operations, or airdrops—better to click a couple more times than to gamble with luck.
