Trading for gold in the trend, don't treat gambling as investment.

I've been in the crypto world for nearly ten years, witnessing too many fairy tales of overnight riches, but the more realistic stories are those of liquidation and zeroing out. The crypto space has indeed changed my life trajectory, but not with fantasies of "hundredfold coins" or "thousandfold coins," but with survival rules summarized from painful lessons.

I still remember when I first entered the market, I had 20,000 yuan full of hope. Later, I experienced the madness of assets soaring to millions, and also tasted the despair of liquidation, debt, and nearly losing everything. Those bitter lessons made me realize: the crypto world is not a casino, but a place where knowledge is exchanged for money.

**First Rule: Trends are friends, don't fight the market**

I never try to guess the top or bottom, because that is inherently a false proposition. Those claiming they can buy at the lowest point and sell at the highest point are, frankly, scams. I only act in the middle of the trend, earning steady profits.

How to judge? Keep an eye on moving average systems, such as the 30-day and 84-day moving averages. When these averages shift from downward to sideways, and then slowly turn upward, that’s a true signal of a trend forming. In an upward market, buy when the price retraces to support levels; in a downward market, sell when the price rebounds to resistance levels. Once a trend is established, it won't easily reverse. Follow the trend, let profits run, and decisively cut losses. I’ve used this logic for many years, and even during the sharp decline of the 2008 market, I managed to earn 35% returns against the trend, relying on timely exits and precise positioning.

**Second Rule: Position management, never give yourself a chance to lose everything**
