Just went through a rage-inducing trade—let me replay it and give myself a reminder.

I originally wanted to snipe the bottom of a small on-chain coin. The depth looked decent, so I just set a default slippage on the fly. Then the market suddenly moved—I confirmed a half-beat late on my side. By the time the transaction got on-chain, it had already been eaten by more than ten percentage points of slippage. To put it simply, it’s like getting stabbed by MEV bots.

I’m angry, but if I think about it, it’s on me: “depth” is dynamic. It might look like there are thick orders on the surface, but once your execution rhythm gets off, the instant liquidity can collapse.

Everyone should have seen the recent cross-chain bridge hack, and when an oracle shows abnormal pricing, the whole network is waiting for confirmation. At this point, the lesson is the same as mine: don’t rush in. It’s better to wait a few blocks until liquidity recovers before you move. I’ve now set a rule for myself: adjust slippage protection in advance, and when routing the trade, prioritize paths that can better withstand sniping/front-running— even if it costs extra gas.

Anyway, if you move too fast you’re likely to get flustered and anxious. Calm mindset is what keeps you away from those sandwiches. That’s it for now.
