Just reviewed a failed trade from last night, and it was pretty stupid: after crossing to L2, I saw the low transaction fee and acted quickly, but the pool depth wasn't enough. I also set a slippage I thought was "sufficient," and when the market moved, I got hit hard, paying twice the gas fee for nothing. To put it simply, low fees ≠ reckless trading, especially with small pools—just one price jump can lock you out.

Later I realized I need to slow down my order pace: first check the trading volume and order book (if there's no order book, then look at the pool size), try a few small tests, don’t go all in at once. Recently, the testnet points expectations also affect my mindset—constantly thinking "Will the mainnet launch tokens?" rushing to meet deadlines, which makes my hands more jittery... Anyway, I’ll treat slippage and depth as essential homework. If there are incentives, I’ll grab some; if not, don’t pay tuition just for a few points.
