A couple of days ago, I was wandering on the blockchain and saw a pool with a slippage that looked "pretty good," almost got tempted to place an order.

But when I opened the transaction path and looked, there were two obviously suspicious transactions on either side—forget about the opportunity, it was basically me paying someone else’s fees: I buy, they raise the price first; I sell, they dump the price first.
The rest is called "arbitrage," but in reality, I was sandwich attacked...
I really wanted to curse myself at that moment, treating my wallet like a wishing well.

Recently, someone linked ETF capital flows, U.S. stock risk appetite, and crypto market rises and falls, sounding quite reasonable, but for me, it’s still the old habit: if I don’t understand it, I don’t act.
If you’re not even sure whether this trade will be sandwich attacked, don’t expect macro narratives to help you check slippage and permissions.
Anyway, I held back that time from confirming, and what I saved was what I earned.
