These days, I’ve seen people complain again about “on-chain queue jumping,” which basically comes down to the issue of ordering: you think that just pressing confirm puts you in line, but in reality, you might be stuck in the middle, or jumped ahead, resulting in larger slippage and worse execution. The biggest impact usually isn’t from large whales; they have tools and channels. It’s the retail traders making small swaps who end up paying extra costs for no apparent reason, thinking it’s just their own clumsiness.

I can also understand why miners/validators’ earnings are often criticized; MEV is like a “road toll,” invisible but constantly deducted. Anyway, now I take an extra step when doing on-chain operations: I try to use private transaction channels or anti-queue-jumping entrances, or simply set tighter slippage limits—preferably failing and retrying rather than being the one whose liquidity gets snatched away easily… that’s how I do it for now.
