Many people watch a KOL: if they win three trades in a row, they start to worship; if they lose two trades in a row, they start to attack.

But those who truly understand trading know this:
A single profitable trade doesn’t prove their ability, and a single losing trade doesn’t prove their level.
Trading is essentially a probability game driven by large numbers. Real skill isn’t judged by one or two trades, but by the final results after 100 or 200 trades.
So if you want to tell whether a KOL really has true skill, don’t look at how much they make today, and don’t look at how many profit screenshots they post.
Set aside a month and continuously record every one of their strategies, every time they take profit and cut losses, and every time their views are realized.
If, after a month, they can still maintain a stable win rate, still keep a reasonable profit-to-loss ratio, and still consistently outperform the market over the long run—
then congratulations. The person you encountered may not be an actor, but someone who truly has a trading system.
Because stable profits don’t come from luck.
It comes from a trading system that has been validated by the market countless times and still manages to fit mean reversion and the law of large numbers.
The biggest cost in trading isn’t losing money.
It’s wasting time on the wrong people.
