Last night, I played the role of a qualified liquidity exit intern again: watching the candlestick chart, I got excited and rushed in at market price, and the slippage directly pressed my face to the ground... Basically, I didn't check the pool depth, and the order wall was as thin as paper. I even split my buy into two parts, but each one ended up being a "thank you for participating" for others. Looking back, there are really three points: don't compete for that one spot during the busiest times; if you really want to buy, slow down and split the orders, be patient and wait for a pullback; and don't believe in "I'll just buy a little, no problem," because even a tiny amount can be lifted in a shallow pool.

Recently, everyone has been complaining that miners/validators are making too much from MEV, and that the order fairness is like a lottery, so I felt like I was being set up... The other person was even teasing me nearby: this isn't trading, it's paying others' wages. Forget it, next time before placing an order, check the depth first, and then control yourself.
