Last night, I was still watching transactions on the chain while singing halfway through, and the more I looked, the more I felt that the so-called "cutting in line" thing, honestly, the person most affected isn't who earns more, but the experience of ordinary people who think "I clicked confirm, why is the price still changing/failing." You think you're queuing, but in reality, someone can cut in line, push you to the back, with high slippage and gas wasted, which really can break your mindset.

Recently, L2s are arguing again about TPS, fees, and subsidies, it's lively, but I'm more concerned about who actually decides the order and whether the rules can be clearly explained. Cheap and fast is of course great, but if fast is achieved by "better queue jumping," then the sense of fairness becomes very mysterious... Anyway, I'm now more cautious in doing things, splitting orders when possible, setting limit prices instead of chasing blindly, earning money or not is another matter, at least I avoid becoming just a "side dish" in someone else's strategy.
