MEV, to put it simply, is "who sees first, who cuts in line first." The ones truly affected are not the people writing bots (they clearly calculate their costs), but ordinary users swapping tokens on DEXs or setting stop-loss orders, experiencing large slippage and distorted transaction prices, and then thinking they are slow. Is it fair or unfair? On-chain, transactions are ordered by priority, but you just couldn't see it before.

Recently, in the group chat, there was talk about certain regions implementing new taxes or regulatory trends. As people's expectations for deposits and withdrawals changed, they preferred to swap on-chain more, which made it easier to get caught in the same congestion wave, giving more room for front-running... Anyway, now I split my orders into smaller parts and try not to rush during peak times. Also, in the group, stop arguing "you don't understand," and instead share more transaction reproductions—that's more helpful.
