Everyone who trades in the crypto world has experienced this moment—an account soaring to a new high, only to crash instantly during a major pullback. It may seem unbelievable, but this is actually the most common tragedy in the crypto space.

Among the players I know, many have gone from a few thousand yuan to millions. But very few can safely hold onto that money until the end.

Most people's stories are similar: a paper profit of over 300,000, a market correction, and the profits vanish in an instant, sometimes even losing the principal. Some are even liquidated directly.

This isn't due to poor market conditions or bad skills; the root cause is the same—not knowing when to take profits.

Many people misunderstand "rolling positions." They think it means constantly placing orders and endlessly adding to positions, which leads to more and more losses. The truly sustainable way to roll positions is exactly the opposite: only trading in highly certain market conditions, and otherwise just holding steady.

**Contract traders losing big money usually fall into these traps:**

1. Forcing trades without a trend. Opening positions blindly when the direction isn't clear, resulting in being beaten up repeatedly.

2. Getting greedy after small gains. Increasing positions wildly when there's a little floating profit, ignoring risk management, and losing everything in a sudden market move.

3. Holding on stubbornly after losses. The stop-loss has already been penetrated, but they wait for a rebound, only to be harvested in the end.

Those who can truly grow their accounts share a common trait: extreme self-control. My own trading approach boils down to three principles, and often I find myself doing nothing:

**Protect the principal first with the first profitable trade**

The money from the first profit should be immediately withdrawn from the original capital. The remaining funds should only be used with profits, which changes the mindset completely. No fear of losing everything because the principal is already safe. This can reduce psychological pressure significantly and improve judgment clarity.

**The more you earn, the more cautious you should be**

Once floating profits reach your target, immediately move the stop-loss line upward to lock in some gains. There's no need to chase the absolute top, but you must prevent giving back the hard-earned money. When the price rises to a certain level, consciously take some profits off the table—this is much more dignified than being wiped out in the end.

**Only trade during trend explosions**

It's not about trading more frequently than others, but about finding highly certain market conditions. When the trend isn't clear, stay out and observe. Use this time to review, learn, and adjust your mindset. When an opportunity arises, focus your efforts—this approach is often much more efficient than daily random trades.

Ultimately, the crypto world isn't short of people who can make money. What’s lacking is those who can make money and still hold onto it.

The real difference between traders isn't how many opportunities they seize, but whether they have the ability to securely keep the profits in their accounts.

Being patient, setting stop-losses, and knowing when to cut losses decisively—master these three, and you'll be qualified to talk about long-term doubling your capital.
