Recently, I’ve seen a bunch of screenshots of “on-chain opportunity discoveries” again. My first reaction isn’t excitement, but rather thinking: is this deal just someone else’s fee?

Sandwich attacks and arbitrage, to put it simply, are about someone being faster than you, knowing the route better than you.
What you see is the price difference; what they see is your slippage.

In the past, I also loved chasing those suddenly hot memes, or rushing in when a celebrity shouted.
But I often bought at crowded times, and the moment of transaction made my heart sink…
Later, I got used to it: when the hype is high, I split the orders into smaller parts, set slippage to a fixed value, and prefer limit orders over market orders.
I’d rather miss out than be the last one to buy at a bad price.
Anyway, when the tide recedes, the shells you pick up on the beach aren’t necessarily treasures.
