Just realized how stupid I was: a simple swap clearly isn't urgent, but I still followed the K-line to chase the pump, and ended up with a huge slippage and got caught at a “surprise price,” almost got sandwich attacked… Basically, I didn't check the depth, the pool was as thin as paper, and I used market order to force through.

Looking back, there are only three things: don't treat slippage as a safety net, split orders if the depth isn't enough, and don't follow emotions with the timing. Especially for pools that just heated up, once the routing jumps once or twice, they start to drift, save a bit on gas, but the price gets completely pushed back, and the loss is even more brutal.

Recently, Layer 2s are arguing over TPS, fees, and subsidies, I just want to say: no matter how fast or cheap you are, a bad route + low liquidity = still get schooled. I'm tired but still going… First, make your trades “like a person,” not “like gambling.”
