Just realized I was so stupid: I wanted to copy a small rebound, saw the order book looked okay, and immediately swept in with a market order, only to have the slippage wipe out the "cheap" price. Honestly, it’s not that I had the wrong direction, I just didn’t look at the depth carefully; the volume hanging there was as thin as paper, and I kept urging myself, "Hurry up and fill." Later, I thought about it—placing orders quickly is actually more important than I thought: better to split into two or three smaller orders and take it slow, or just set a limit order and wait a bit, instead of competing with my emotions.

Recently, that mainstream public chain is upgrading/maintaining, and everyone in the group is guessing whether the ecosystem will migrate. I’ve become even more timid: when node liquidity shrinks before and after the upgrade, the first to get hurt are people like you who place urgent orders. Forget it, this time I’ll take it as paying tuition—remember that "slippage tolerance = self-deception."
