Five years ago, when I stepped into the crypto world, I also experienced the despair of my account shrinking by half in an instant. Looking at the rapidly declining Candlestick Chart, I realized: this market is the least forgiving, yet the fairest—it punishes the reckless and rewards the disciplined.

After spending three years repeatedly trying and failing in actual trading, I gradually found a rolling warehouse strategy that suits me. Starting from 300U, I worked my way up to 100,000U, without relying on luck or anything magical, just strictly adhering to three rules. Today, I share these insights in the hope of providing some reference for those of you still struggling in the market.

**The first iron rule: Always split the principal in half; as long as you're alive, there are infinite possibilities.**

I call this the "Half Position Opening Rule"; to put it simply, it is the underlying logic of risk management.

Take 300U for example, I will only use 150U to operate with real stakes, while the other 150U is like leaving myself a way out - locked up, not moving.

Why do it this way? There are two key reasons. First, the market can suddenly make a "spike" when you least expect it, and your order might instantly trigger a stop loss, but with this reserve fund, your principal won't be severely impacted. Secondly, and more importantly— it can keep your impulsive self in check. Many people, once they lose money, become impulsive and start averaging down, which leads to greater losses, ultimately leaving them with no escape.

When there are earnings, for example, if I make 50U and my account becomes 350U, I will readjust the ratio: 175U for trading, and 175U continues to stay idle. Always maintain this 1:1 balance. No matter how the market fluctuates, I am not afraid, because I always hold the option in my hands.

The core of this idea is actually: first ensure that the principal is alive, and profits are secondary. Do not seek to get rich overnight, but rather strive to avoid putting yourself in a position with no chance of recovery.

**Second Iron Rule: Take profits in segments; greed won't get you the meat**

Many people ask me when to close their positions, but there is no absolute answer. My method is: release profits in stages when you see them, don’t wait until that moment filled with regret.

Suppose I operate a position in a certain coin, and I have a floating profit of 30%. I will immediately close one-third to lock in the profit. If it continues to rise, when it reaches 50%, I will close another one-third. The remaining one-third is what I truly use to "bet" on the subsequent market trends. The advantage of this approach is that even if it drops later, I have already secured the core profit, and my mindset will be particularly stable.

Why do this? Because I have seen too many greedy people staring at the screen, looking at 30% profit, hoping to wait for 50% or even 100%. As a result, the market turns, and profit becomes a loss, even the principal gets hurt. I don't want to be that kind of person.

**Third Iron Rule: Once the stop-loss line is set, there can be no haggling**

The last one may also be the hardest to execute.

Before opening a position, I will accurately calculate the stop-loss point each time. For example, if I buy at 8000, I set a stop-loss at 7900, exiting with a loss of 100U. Once the price reaches that point, without any hesitation or luck, I immediately close the position.

Human nature is to make excuses for oneself: maybe it's just a temporary pullback, maybe I should wait a little longer. But I tell myself that these thoughts are all illusions; only strict execution can lead to a long life.

Three years of real trading has made me understand that those who survive until the end are not necessarily smarter than others, but rather more disciplined. Market fluctuations will never stop, but if you establish your own system, persist in rolling over positions, taking profits in batches, and enforcing strict stop-losses, then every fluctuation will just be an opportunity to make money, rather than a deadly danger.
