The craziest account stories I've seen aren't about getting rich overnight, but about dying suddenly.

Starting with 5,000 yuan, growing to over a million in half a year—this isn't a myth in the crypto world; real cases happen every year.

But what is the more common ending? An account that was floating with a 500,000 yuan profit the day before, and after a single pullback the next day, the profits vanish instantly, sometimes even dropping to zero.

This isn't just bad luck; fundamentally, it's a structural error in trading logic. Many people attribute failure to reasons like insufficient technical skills, problematic indicators, or misjudging the market. But my observation is that these are just surface issues. The real fatal flaw boils down to two words—**not knowing when to stop**.

The concept of rolling positions is often misunderstood. It doesn't mean trading every day or frequent operations. True rolling is only taking action during those "worth risking everything" market conditions; at other times, just rest as needed.

From my observations, the main behaviors leading to contract losses are: forcing trades when the market lacks momentum, aggressively adding positions after small gains, and stubbornly holding onto losses without cutting.

Conversely, those who truly manage to grow their capital almost always show excessive restraint.

I've used a rolling position framework for many years. The logic is simple, but execution is counterintuitive.

**Step 1: Take profits immediately after the first winning trade.** Once the first trade is profitable, withdraw the initial capital right away. Use only the profits for subsequent trades. The benefit of this approach is that, regardless of how volatile the market becomes later, your mindset remains stable.

**Step 2: The more you earn, the smaller your bets.** When floating profits reach 50%, move the stop-loss up to the cost price. If you push it further up, aim to lock in at least 30% profit. The idea isn't greedily riding the last bullish candle but ensuring you don't return to the starting point.

**Step 3: Only act when the timing is right.** Rolling isn't about how frequently you trade but whether you can catch the true breakout of a trend. When the market hasn't clearly established a direction, it's better to stay on the sidelines and wait. Without enough volatility, taking risks isn't worthwhile.

Finally, I want to say: many people lose money not because they can't make profits, but because they lack the ability to hold onto those profits once gained. In the crypto world, the real difference isn't how many times you catch the bottom or how many opportunities you seize, but whether you can preserve the profits you’ve earned.

Remember this logic: those who can patiently wait, know when to take profits, and can decisively cut losses are the ones qualified to talk about doubling their capital.
