It feels like this on-chain “queue jumping” mainly affects two types of people: one is retail traders who think that once they click, their trade will execute in order, and the other is liquidity players who place orders near the floor price / sweep for liquidity (including me, who watches the order wall closely). It’s not that someone is necessarily exploited badly, but the “fair” matching you think you’re getting is often just psychological comfort.

The reason is simple: for the same buy and sell, once the order sequence has been tampered with, the execution price, the counterparty, and even whether you can complete the trade all change. Especially with NFT floors that have thin liquidity, if someone runs ahead of you, your order can shift from “getting a cheap deal” to “helping other people raise their bids,” or else get squeezed in the middle and end up paying a toll. Recently, the collapse rhythm you see in chain games—like inflation plus studio-driven boosting/manipulation—also feels similar. When the rules are a bit skewed, the spiral ends up with whoever takes things seriously getting screwed… Anyway, I’d rather chase one or two fewer trades than be the one “educated” by the sorting order.
