最近看链上那种三明治+套利的痕迹，心情挺复杂的。

You think you've quickly caught a bit of price difference, but once you enter the pool, the slippage feels like someone has pre-written the script, and the fees and losses add up, essentially working for others.
Especially during the period when new L1/L2 incentives boosted TVL, everyone was rushing to "mine, transfer, sell," liquidity would come and go quickly, and the more urgent the transactions, the easier it was to get sandwiched.
跨链操作我都要反复确认，更别说追这些了。

我现在基本不再追解释了，很多时候就是随机——你没做错什么，也可能刚好站在别人更聪明/更快那一侧的对手盘里。
Anyway, I prefer to be a bit slower, place small orders, split into batches, avoid touching if possible, and sleep more peacefully.
