Last night, I was reviewing my transaction history and found that I still left "unlimited authorization" on a few old contract addresses, almost made me laugh out loud... To put it simply, this thing is like sleeping with the door open, nothing usually happens, but when a problem occurs, everything gets cleared out immediately. When the economy of a contract/game chain crashes (inflation + studio pumping to the sky, coin prices spiraling), project teams get anxious, contracts get hacked, and if your permissions are still active, you're just waiting to be a cash machine. Now, before I place an order, I dare to go all-in, but before sleeping, I always do two things: reduce positions and revoke permissions. I can tolerate emotional trading, but if I don't revoke permissions, I really can't sleep.
