On-chain this "cutting in line" essentially means who has the ordering rights. You think that once you click swap, it should execute in order, but instead you're stuck in the middle as fuel: slippage increases, the execution price gets worse, or you're even directly rolled back with a face full of question marks. The biggest impact isn't from "institutions," but from ordinary people who don't have time to monitor the mempool, especially those who get excited and quickly trade market orders during hot spots.

Recently, there's been a lot of talk about modularization and the Layer 2, with developers discussing passionately, while user-side concerns remain: I just want it cheaper, and not to be cut in line... No matter how many narratives there are, the unfair sorting—this pile of shit—still stinks.

My own simple way to avoid impulsive orders is: whenever I see a candlestick pattern, I first close my wallet, check the transaction distribution/on-chain failure rate, or just set a small limit order and leave it there. If after ten minutes I still want to buy, then I consider it. Otherwise, that quick reflex is basically paying others for MEV.
