I took a quick look at my position in the middle of the night, clearly just a small floating loss, but my mind immediately started to exaggerate: Should I cut my losses, is the liquidity too thin, did I get hit by slippage again... Conversely, when I have floating gains, I sleep more soundly, at most thinking I'll check again tomorrow. Honestly, loss aversion is so irrational, the money I make feels like "it might fly away," while the money I lose feels like "it's already been cut from my body," and my emotions grip tighter.

Later, I set a simple rule for myself: before entering a trade, clearly write down the maximum tolerable drawdown and exit conditions; if triggered, exit, if not, don’t change parameters in the middle of the night; also, place orders in layers, don’t expose yourself all at once to the volatility of a single spike. Recently, the "attention mining" concept in social mining and fan tokens is quite similar to this logic—when attention is lost, the mental pain is even worse than losing money... Anyway, I’ll only do what I can calculate clearly for myself; sleeping is more important.
