The third time I saw someone excitedly show off "I’m arbitraging on the chain," I couldn’t help but laugh: what you see as an opportunity, others see as your slippage and transaction fees.

The sandwich thing, to put it simply, is just lining up to cut you with two knives—thinking you're the smart money, but actually you're just a side dish in liquidity.

Recently, a wave of memes and celebrities shouting out has caused attention to shift so quickly it’s like short video scrolls.
Veteran players advise newcomers not to take the last baton, but I think they should add: don’t be the last piece of bread, stuck in the middle and still paying.
Anyway, before I place an order, I first try to keep the slippage within a tolerable range; if I can’t, I just give up—missing out is better than contributing as a fee.
