Recently, people keep asking me if seeing "sandwich" and "arbitrage" on the chain is an opportunity... When I see this kind of excitement, my first reaction is not to think about making money, but to ask: who is actually paying for these transaction fees? Honestly, you might think you're catching a bargain, but they might just be casually recycling your passing bottle of mineral water.

What's even more awkward is that those on-chain data tools/tags are also criticized for being outdated and potentially misleading. You chase after tags, but in the end, it's like looking in a mirror in an elevator: thinking you've seen clearly, but it's just delayed self-reflection.

I no longer try to explain; I accept randomness. The only things to do are: don't get too emotional, don't leverage too much, and before trading, think for one more second, "Am I just paying someone else's fee?" That's all for now.
