Simplifying complex matters and repeating actions is the real challenge.

In 2017, I entered the crypto world with 20,000 yuan. By 2025, I had accumulated assets worth 50 million. Over these 8 years, I have traded using the same system, and many friends around me think this method is too naive—indeed, I also refer to it as such. It is this seemingly useless "foolish system" that has allowed me to survive multiple market cycles and still shout out financial freedom.

Now I have decided to archive this system, but before that, I want to share it. This is not investment advice, just a heartfelt message from someone leaving the exchange.

**The core secret is just three lines**

The system is so simple it’s almost absurd—all trading decisions are based on three things.

The 50-day moving average is used to gauge short-term direction. If the price is above it, it indicates a bullish trend; if below, a bearish trend. The 200-day moving average is the dividing line between bull and bear markets. When the 50-day crosses above the 200-day (called a golden cross), it usually signals that a bull market may be coming; vice versa. Volume tells me whether this rise is genuine or fake. Breakouts without volume are all false signals.

Just these three lines, and I ignore all other complex indicators and news. I only wait for these three lines to give me signals.

**The moment to bet big**

There was a key moment in 2017 that I still remember.

When Bitcoin surged past $5000, the 50-day line was firmly above the 200-day line, and volume was three times the six-month average. I clearly knew that the system was giving a green light. That time, I made a big decision and invested most of my funds.

Many people said I was crazy. But that trade ultimately earned me more than five times. Not because I had any prophetic ability, but because I trusted the system’s signals.

**Why it works**

The reason this system has lasted so long is simple: it’s actually about following the trend. Moving averages are lagging indicators, yes. But because they lag, they help filter out false signals. The biggest pitfall in trading crypto is chasing perfect entry points, leading to frequent stop-losses and being forced out.

Choose an effective signal and stick to it—that’s the real secret to making money.
