As a seasoned trader coming from traditional finance, I want to share a methodology that has been tested through years of experience in the crypto market. From spot trading, futures, to crypto assets, the core logic is actually very unified—trend recognition, risk control, disciplined execution, that's all.

Many people think the crypto world is very complicated, but the logic of making money is actually quite simple—almost cruel. It boils down to four steps: selecting coins, buying in, position control, and selling. I will break down the practical details of each step clearly.

**For selecting coins, focus only on MACD golden cross**

Open the daily chart, filter for coins where MACD forms a golden cross above the zero line. Why choose this? Because this is when the trend is most clear, filtering out 80% of weak assets. Less hassle.

**The critical line for holding positions is the daily moving average**

Switch to the daily K-line, look at only one moving average. If the price is above it? Hold firmly. If it breaks below? No matter how much it has risen, get out. This is not just insight, but trading discipline. Overthinking and hesitation are the roots of losing money.

**Timing the buy: double confirmation**

A coin breaking the daily moving average isn't enough; the key is that volume must also increase simultaneously, standing above the average volume line. Only then is it a true confirmation, and you can enter directly. Trend resonance is the most comfortable entry point.

**Selling tests your patience and is the most critical**

Don’t sell everything at once; do it step by step. When gains exceed 40%, sell one-third first—this eases your mind and leaves some cash in your account. When it reaches 80%, sell another third—this locks in most of the profit. The last portion? Wait and see. If it suddenly drops below the daily moving average one day, regardless of profit or loss, clear the entire position.

The hardest part of this rule is execution. You know the market might rebound the next day, but you still sell. It feels uncomfortable. But this discomfort precisely protects your principal. Money only flows to those who can overcome human weakness.

As market volatility increases, the importance of strategy becomes more evident. In a bull market, impulsively chasing highs can trap you; in a bear market, panic selling can cause you to miss rebounds. Truly profitable traders never rely on luck or gambling mentality, but use a cold, systematic approach to counteract market temperature changes.

Protecting your principal is safeguarding your chance to come back. The opportunities to double your investment in the next cycle will always belong to those who survive until the end.
