Sandwich attacks and arbitrage, huh? You think you're seeing an "opportunity," but honestly, most of the time you're just paying others' transaction fees. You set up a seemingly clever swap, but when the order packing changes, with two trades sandwiching the market, that tiny "profit" in your slippage turns into someone else's gas fees and tips... I watch the mempool until my eyes hurt, and the more I watch, the more anxious I get: you're calculating your returns, but they're calculating whether you'll be a sheep.

By the way, recently the group has been talking about stablecoin regulation, reserve audits, and de-pegging rumors, with emotions swinging wave after wave. The more anxious people get, the more they want to rush, and the more they rush, the easier they get caught in the trap—it's a closed loop.
My current approach is very crude: if I can set a limit price, I do; I push the slippage to the max, and if I can't, I just give up. I no longer chase explanations; I accept randomness.
