Don't be blinded by half-hour gains from reckless trading

Last year, a friend used a rolling position strategy to turn 3,000 USDT into over 90,000 USDT in half an hour, feeling ecstatic and unable to sleep, sending red envelopes in the group and showing off his profits everywhere. But the next day, he became overconfident, thinking he could reach 500,000 USDT with one more try, and went all-in. Unexpectedly, the market quickly reversed, not only wiping out all his profits but also losing most of his principal.
Later, he lamented that the explosive profit in that half hour had directly blinded him. I’ve always kept this in mind.
The most deadly aspect of rolling positions is not the loss itself, but the brief taste of sweet success. Once you taste explosive profit, you want to replicate it; if you miss the market, you rush to enter and gamble. When impulsive, all rationality disappears. In fact, most short-term gains are luck-based, not because of precise judgment. The real test is whether you can stay clear-headed when your account doubles.
Here are some practical trading principles: after doubling your profit, first withdraw the principal, only gamble with the profit; even if the market pulls back, it won’t harm the core; after two consecutive profitable trades, actively pause and rest, as the feeling of riding the trend can easily lead to reckless mistakes; once your account size grows, forcibly withdraw part of the profits. No matter how good the numbers look on paper, cashing out is what truly belongs to you.
I’ve seen too many people start to decline the moment they share a screenshot of their account’s peak. Explosive profit itself isn’t scary; what’s frightening is that you mistakenly believe this luck will become the norm.
