I'm increasingly feeling that on-chain "queue jumping" isn't some kind of mysticism; the biggest influence comes from those who think they're playing by the rules... especially those doing swaps, margin liquidations, or relying on oracle price feeds to trigger conditions. You think that once you click, the trade is executed, but in reality, it might have been inserted by others two or three layers deep, with the price and path manipulated, and that small difference in your account is just your "tuition fee."

To put it simply, MEV/ordering isn't just about front-running to profit from price differences; it turns "fairness" into an illusion: the same operation, some can see it first, act first, and even treat you as liquidity. Recently, many new L1/L2 chains are offering incentives to boost TVL, and I understand the complaints from veteran users about "arbitrage and selling," because with incentives, the chain gets more crowded, queue jumpers increase, and the worst experience ultimately falls on ordinary users.

Now I myself pay more attention to the update rhythm and latency of oracles; slow price feeds and chaotic ordering can easily lead to incidents where it feels like "even though the time hasn't come, you're still being penetrated"... Anyway, split the orders if possible, set slippage if you can, don't rely too much on "being fast."
