For friends just entering the crypto trading world, here’s a word of advice: don’t think about getting rich overnight. The market never shows mercy to newcomers, and one fatal mistake could eliminate you from the game.

So the first step is to learn capital preservation. Let me share 5 hardcore trading rules:

**1. Reduce the frequency of trades**
Trading does not mean frequent operations. When the market is unclear, staying out of the market is the smartest choice. Many losses ultimately come from "forcing participation," but sometimes stopping can save you.

**2. Always set a stop-loss**
A stop-loss is not about giving up; it’s the bottom line of risk management. Trading without a stop-loss is essentially gambling and can lead to sudden slumps. Setting your stop-loss points in advance helps cap your losses.

**3. Control your position size**
Don’t put all your funds into one trade at once. Moderate position sizes keep you flexible, allowing room for action when the market suddenly changes, and help maintain a stable mindset.

**4. Only trade what you understand**
Don’t blindly follow trends you don’t understand. Missing an opportunity isn’t scary; opportunities are available every day. Focusing on what you’re familiar with is the right way.

**5. Manage your emotions**
After a series of losses, the easiest mistake is to add to your position—this is a typical emotional reaction. Stay calm, replace anxiety with rational thinking, and avoid turning small losses into big ones.

**Final words**
In trading, how much you earn is less important than how long you survive. Protect your capital, operate steadily, and be patient—these are the essential lessons for long-term players. Opportunities will come, but only if you’re still in the game.
