Recently, everyone has been chasing memes and celebrities shouting, rushing in at the slightest call.

But I'm actually more worried that "you think you're trading with the market," but on-chain, it's often a battle of ordering.
Others think that as long as you're quick and add a little gas, you can win.
In reality, you're publicly queuing, and someone behind you can see what you're about to do, then cut in line, sandwich you, and leave the slippage and fees to you.

To put it simply, MEV not only affects big players, but the ones who suffer the most are often small traders who frequently change positions: paying a few extra times, getting a little less each time, and the accumulated impact is quite damaging.
Fairness isn't just a slogan; if routing/aggregators default to exposing users to sandwichable paths, I really have zero tolerance...
I now prefer to trade fewer times, set strict slippage, at least not be the last in line.
Anyway, there's no "cut-in-line penalty" on-chain, so you can only be more cautious yourself.
