There is a very painful phenomenon in the crypto world—someone turns 5,000 yuan of principal into a million in half a year, only to be instantly wiped out and go to zero in a single trading day. Just moments before celebrating a 500,000 profit, the next moment the account is a blank sheet. This is not a story; it’s a real scene played out every day in the market.

Why do most people inevitably lose money in contracts? Ultimately, it boils down to two words: greed. Going all-in,爆仓 every night, never learning what "waiting" truly means. The core logic of rolling positions is actually very simple—it's not about frequent operations, but about decisively striking in the face of the most violent market conditions.

The most common pitfall for beginners is this: making a little profit and immediately adding to the position, only for a wave of pullback to wipe the account to the bottom. The correct approach is completely opposite. Profitable on the first trade? Don’t be greedy; withdraw the principal entirely and only roll with pure profits. The benefit of doing this is that your mindset will be much more stable, and the risk can be cut in half directly.

The practical rule I’ve summarized is this: every time the account reaches a 50% return, immediately move the stop-loss to the cost price to completely prevent losses. When the account doubles, at least withdraw 30% of the profit as a risk cushion. The earlier you master these details, the longer you can survive in this market.

To put it simply, most people don’t lack money; the problem is that they can’t hold onto it. Not taking profits after earning is equivalent to giving your chips to the market. When the trend reverses, it’s too late to regret. Instead of being passively forced out, it’s better to actively harvest. Market opportunities are fleeting—when it’s time to act, don’t hesitate. Rather than being confused by volatility, learn this hardcore logic to make each trade more rational and more in control.
