Last night after work, I checked the blockchain casually, clicked on a pool, and the slippage suddenly became outrageous. At that moment, I felt something was off... Sure enough, the two transactions before and after trapped me clearly. You think you're "catching opportunities," but you're actually just giving others a chance to collect fees. The small profit in your wallet hasn't even warmed up before being eaten away. Recently, that mainstream public chain is undergoing upgrades/maintenance, and the group is guessing whether projects will move. I think such timing makes it easier for the "fast hands" to eat the meat and the "slow hands" to become fuel.

To put it simply, with sandwich attacks and arbitrage, what you see as an opportunity, others see as you. If you really want to do it, don’t chase the hype and rush for traffic. Instead, do fewer trades, and first clean up the details like paths, slippage, and transaction speed. I’ve become more laid-back now—before executing, I look at the mempool and depth a couple more times. If it doesn’t look right, I withdraw. Missing out is fine; at least I won’t be someone else’s performance metric.
