Just almost got wrecked... When copying the address, I accidentally pasted the transaction route into another aggregator. Before confirming, I took a quick look at the slippage + estimated proceeds, and noticed something was missing. I instantly snapped out of it. Later, I checked a similar on-chain transaction—classic sandwich attack: I thought I was "catching an opportunity," but it turned out to be someone else's fee + MEV small treasury.

To put it simply, with arbitrage, you calculate the price difference openly, but others are calculating your urgency secretly. Especially recently, with the staking and shared security "yield stacking" debates getting pretty heated, I'm more worried about the layered complexity—eventually, the small profit you make gets slowly worn down by slippage, fees, and traps.

Now, I’m just being honest: split large orders into smaller ones, set limit/low slippage, and if I see open interest and funding rates drifting, I reduce a bit first... Anyway, discipline is more reliable than "quick fingers."
