Today I came across a bunch of screenshots of "sandwich + arbitrage opportunities," to be honest, the small profit you see is often just someone who has already set the table with knives and forks, and in the end, you still have to pay the gas when checking out. Especially during congestion, when the packing order gets messy, you think you're profiting from arbitrage, but it turns out you're just feeding the bots a chicken leg.

Recently, I’ve been quite aware of the complaints about on-chain data tools and address tagging being outdated: you’re watching the "suspected MEV" label a bit too slowly, and they’ve already changed their alias and run away… Anyway, I trust data more now, but only raw data plus my own view of the mempool. My intuition is too easily fooled by a big bullish candle. If I really want to go for it, I’d first write a small script to lock the slippage and gas cap; otherwise, I’d rather not do it, even an impatient person has to admit it.
