Recently, I've been looking into the MEV "queue-jumping" tricks again. Basically, whoever can see first and get in line first can take others' slippage as pocket money. The impact isn't just on some whales; it's more about the experience of ordinary people who think, "I just want to swap a coin, why am I still being overcharged?" Over time, this makes the chain increasingly resemble a pump-and-dump machine, and the sense of fairness is worn down.

What's even more annoying is that it amplifies with hot topics: when cross-chain bridge hacks happen, everyone instinctively waits for confirmation; the same with oracle errors—suddenly, there's a delay consensus forming on-chain. But the more you wait and hesitate, the clearer the signals you give to the ordering players: which orders will be canceled, which will go through aggressively. The result isn't fate but a matter of probability—each time you place an unprotected order or skip using limit/private channels, your risk of losing increases slightly. Anyway, now I just do small tests with unfamiliar pools first; if it takes longer, I accept it.
