I just looked at an address—there are dozens of authorization records still hanging on-chain, and some allow unlimited transfers. What’s the difference from not locking the door when you go to sleep?

Honestly, there are so many cases where large on-chain transfers are interpreted as “smart money,” and it’s hard to tell what’s real and what’s not. Instead, it’s the abnormal operations that are more worth watching—for example, an address that revokes the authorization right after it’s done using it each time. It costs a bit more in gas, but at least it’s reassuring. I’m used to taking screenshots and saving them as a record for myself, even though it doesn’t really help much.

In any case, with things like unlimited contract approvals, the less the better—use them up and then revoke them. Borrowed money can’t withstand liquidation either.
