I just paid another "tuition" fee.

I originally wanted to switch to a smaller coin with a small position, and to save effort, I used market price directly,
but I slipped on the slippage, and the transaction price was quite far from the line I was watching...
Honestly, it's still my laziness; I didn't check the depth first, and the pool was as thin as paper,
a slight push was enough to push me up.

Looking back, the problem isn't the "direction," but the rhythm:
When I get impatient, I want to finish it in one bite, and the more I rush, the easier I get thrown off by the price.
In the future, for such low-liquidity situations, I’d rather split it into two or three times, place limit orders,
slow down a bit, at least have a clear mind.

Recently, everyone has been complaining about validators eating MEV and unfair ordering,
I actually can't judge who is right or wrong, but my feeling is:
the more casual you are, the more likely you are to become just a small corner of someone else's profit.
I need to be reminded: check the depth first, then place the order,
don't compete with emotions for speed.
That's it for now.
