In this market, the most important lesson I've learned is actually very simple—rules are greater than talent, and surviving is more crucial than getting rich quickly.

I've been in the industry for over eight years. I still remember starting with only fifty thousand yuan to test the waters, and now my assets have grown over a thousand times. But what this experience taught me isn't how to double my money quickly, but how to survive through each cycle.

I've seen too many stories of friends around me. They thrive in bull markets, their account numbers constantly refreshing, only to be completely wiped out after a big drop. Why can some endure over ten market reshuffles, while others can't survive even one crash? Honestly, it all comes down to whether risk control is in place.

**My Trading Ironclad Rule: The Five-Position System**

Divide your total funds into five parts, and each trade uses only one part. It sounds conservative, but that's why I’ve made it this far.

Single mistake? Losses are at most 2% of the total capital. Five consecutive wrong judgments? The total drawdown is only about 10%, which won't hurt the bones. But this doesn't mean being conservative means giving up on profits—I've set a profit target of over 10% for each trade.

This way, losses only bleed a little, while profits can be substantial. In the long run, this risk-reward ratio ensures an upward profit curve.

**Distinguish Between Downward Rebounds and Upward Corrections**

I generally avoid rebounds during a downtrend. Many people see the coin price drop by 50%, 70%, and try to buy the dip, which is no different from grabbing a falling knife. The real opportunity lies in sudden pullbacks within an uptrend—that's the real point to bet on.

**Only Look at MACD on Charts**

I don't play with those overly complicated indicator combinations. I focus solely on MACD.

When MACD shows a golden cross below the zero line and then crosses above zero, that's my most trusted buy signal. Conversely, if it forms a death cross and dips below zero, it's time to consider exiting. Simple and effective, much more reliable than those flashy theories.

Over eight years, these principles haven't changed. Rules have restrained my desire for quick riches but have protected my principal. In the crypto world, those who survive the longest are often not the ones gambling the most aggressively, but the most disciplined ones.
