I've been watching MEV recently and it's making me a bit anxious. To be honest, the biggest impact of on-chain "queue jumping" isn't on the experts, but on those who think that once they've clicked confirm, they're locked in: slippage gets eaten, transactions get distorted, and in the end they just think they're slow. When doing small arbitrage, I can actually accept slowness because it's at least predictable; what I fear most is chaos—if the order gets jumbled, all expectations shatter, and strategies can only rely on luck.

There's also another point that's quite annoying. Recently, I've seen some on-chain data tools and tagging systems being criticized for lagging behind or even misleading, and I agree: you think you're looking at the "facts," but you might actually be seeing a narrative someone wants you to see. Anyway, I now prefer to do two fewer trades first, to clearly understand the transaction paths and reasons for failure. Otherwise, when emotions kick in, the most certain loss is myself.
