I find that many people are not lacking in skills, but their positions are too "full." When spot prices pull back, they panic and want to cut; when contracts get emotional, they think about doubling, but the result is either they can't hold on or they get wiped out directly. To put it simply: first set aside the amount of money you can sleep peacefully with, and only then talk about trading.

Right now, I basically treat spot as a warehouse, don't check it hundreds of times a day; use contracts only to adjust the rhythm, always leave buffer, and reduce when health feels uncomfortable—don't argue with yourself. By the way, recently there's been a lot of fuss about privacy coins/mixing coins and their compliance boundaries. I just take the risk as part of the cost, not betting on platform or regulatory moods. Oh, and I have a bad habit: I screenshot key parameters so I can review later and understand what I was thinking at the time.
