Recently, someone was talking about "sandwich/arbitrage" again, and every time I see it, it feels quite complicated: you think you're catching an opportunity, but you might just be paying someone else's "on-chain toll."

In plain terms, on-chain isn't inefficient; it's just that someone is specifically relying on your impulsiveness to make a living.

The narrative change speed is faster than protocol upgrades. If I really wanted to act, I'd rather be a step slower, make fewer trades, and not want to be KPI in someone else's MEV chart.

As for trusting data or intuition? I trust data a bit more, for a simple reason: intuition is often just hallucination from not sleeping enough last night.
Let's leave it at that.
