K-line movements flicker on the screen, like a patient's electrocardiogram. But my heart is no longer moved. This is not enlightenment, just the result of lessons learned through repeated blows.

I still remember when I first entered the cryptocurrency world; I was also a fanatic who watched the charts day and night. During the 2017 bull market, seeing the numbers in my account soaring, I truly thought I had cracked the code to wealth. But the market slapped me—only those who have truly experienced the feeling of sliding down from the peak understand how painful it is.

Seven years have passed in the blink of an eye. Most of the friends I "surfed" with back then have disappeared from this market. Surviving until today is not because I am smarter than them, but because I have gradually figured out my own set of survival rules. Today, I want to talk not about a trading holy grail, but about what has kept me alive—the three-layer filtering system, plus a few ironclad rules.

**Layer One: Genuine heat is the premise**

In my early days, I saw every K-line as an opportunity, eager to seize all fluctuations. The conclusion? The more frequently you trade, the faster you lose. Now I understand that doing less is better than doing more.

I only look at those assets that truly have momentum. But having momentum alone is not enough—what matters is whether they can hold their ground. If a coin drops for several days in a row without a decent rebound, I exit immediately. This usually indicates one thing: the main funds have left.

**Layer Two: Follow the monthly chart, don’t go against the trend**

The trend is your friend; going against it is your enemy. I treat the monthly chart as my guiding rod. When I open the monthly chart, if the trend indicator does not show a clear bullish alignment, I don’t even bother looking. The market’s momentum is far stronger than you think. Trying to go against it? That’s just fighting yourself.

**Layer Three: Lock in position, wait for confirmation**

Good opportunities don’t come every day. I prefer to wait rather than jump into a suboptimal entry point. The market has taught me that patience is the greatest asset.
