Recently, I've been looking at sandwiches and various "arbitrage" strategies, and honestly, you think you're picking up money, but often you're just paying a toll for others. I used to chase after explanations: why did my swap, which clearly had slippage set, still get sandwiched; then I thought, never mind, I won't chase explanations anymore, the randomness is too high, on-chain there are always someone faster, closer, or better at calculating.

Now I'm more concerned with whether this counts as an "opportunity." If your advantage is just spotting a price difference, it's probably already embedded in someone else's bot; all you can do is make the path, timing, and amount look more like a regular user, giving fewer signals. By the way, recently everyone has been comparing RWA, US bond yields, and on-chain yield products side by side. My intuition is: those "yields" on-chain are often just a different packaging of complex fees, so don’t just focus on APY—think carefully about who is paying this money. Anyway, I now prefer to go slower and not have a terrible experience.
