Recently, I saw someone talking about sandwiches and arbitrage, calling it a "chance."

I increasingly see it as a kind of emotional test: you think you've found a bargain, but often it's just exchanging slippage and fees for a different name, especially on-chain where impulsiveness can make a transaction feel like a gentle push.
I'm not saying you can't do it, but you have to admit—most of us are not "making money," we're "participating in a queue designed by others."

And then there are those opinions that link ETF capital flows, US stock risk appetite, and crypto market rises and falls—reading too much of that can make your hands itch, but on-chain itching easily turns into someone else's fees...
What I care more about now is: is this a trade I’m willing to repeat long-term, and is the experience comfortable?
Forget it, I won't talk about how to prevent it; I’ll just lower my trading frequency first.
