Recently, watching transactions on the chain, MEV basically means "queuing" not in order: you think you're waiting in line at the window, but someone slips in from the side and conveniently takes the price you just reported. The biggest impact usually isn't from big players (they can negotiate conditions anyway), but from ordinary people who just click swap and leave, facing slippage and failure fees, their mindset also gets worn down.

Now there are a bunch of AI agents/auto-trading claiming to "automatically help you catch opportunities," but I see it more as amplifying the efficiency of cutting in line... Tools aren't wrong, but when it comes to security and permissions, you really need to pay attention to the details, or it's like handing your wallet keys to a stranger driver—your car might go fast, but whether you lose it or not, you'll only see on-chain records afterward. Anyway, I still stick to my old habits: if I can set a limit price, I set it; if I can split orders, I split; I avoid chasing those few seconds of "smart money."
