Back in 2017, I sold my marital home, mortgaged and borrowed a total of 3 million, and poured everything into the crypto space. Bitcoin had just broken through 5,000 yuan, and everyone around me thought I was crazy. But I knew in my heart—I wasn’t gambling, I was executing a system. At that time, the 50-day moving average had just stabilized above the 200-day moving average, and the trading volume was more than three times the six-month average. This was the signal I had been waiting for.

That wave was the first time I saw figures in the tens of millions. Now, eight years later, the last trade has been completed, and my account balance is stuck at 80 million. I’ve decided to retire.

Not because I can’t spend the money, but because I’ve realized a truth: Money in the crypto world is endless, but life is only lived once.

**The core system is that simple**

Three lines determine all my entries and exits: the 50-day line for short-term trends, the 200-day line for judging bull or bear markets, and trading volume to verify the authenticity of funds.

When the price rises above the 200-day line and the 50-day line crosses upward to form a golden cross, that’s a clear bullish signal—enter. Conversely, breaking below the 50-day line, especially with collapsing volume, is a danger signal—exit.

Sounds stupid, right? In 2018, when a certain coin suddenly surged, I only invested 12% of my position according to the system. Later, it halved again and again, ultimately dropping 80%. But because I wasn’t fully invested, I came through unscathed.

Diversifying your position isn’t cowardice; it’s a necessary condition for living long enough.

In eight years, I haven’t broken these three ironclad rules. The system is so simple, so straightforward that many look down on it. But it’s this simplicity that has allowed me to go from a 3 million gambler to the person I am today.
