These past few days, watching the slippage on DEXs, the more I look at it, the more I think that "sandwich/arbitrage" is like this: you think you've found an opportunity, but most of the time you're just helping others collect fees. Especially when you shake your hand and use market orders, then set the tolerance as if it costs nothing, the moment the trade executes, you feel a chill: this isn't trading, it's like giving a year-end bonus to robots...

Now I place orders just like ordering takeout, first checking the delivery fee (slippage + fees), if something feels off, I split the order or just cancel, rather miss out than turn it into fuel. By the way, the NFT royalty dispute also seems pretty similar: you want creators to earn more, but when secondary liquidity tightens, it ultimately shifts the costs back onto ordinary people through other channels. Anyway, I’ll just set my stop-loss first, tough talk aside, but the money is still mine.
