From the Beijing basement to Lujiazui, I have stepped on countless pitfalls over these eight years.

In the winter of 2017, in a 5-square-meter basement with no heating, wearing two layers of clothes and a quilt. 87 yuan in my bank card. Serving tables during the day, watching K-line charts at night. At that time, I only had one thought—survive.

Eight years later, over 38 million in my account. It’s not luck, but the price paid in blood for four lessons.

**Lesson 1: Rapid Rise Means Death**

During the 2017 bull market, a certain altcoin surged 320% in ten days. I went all-in with 80,000 yuan. On the third day, it plummeted 18%, losing 60,000 yuan in a week. I thought I had misread the market.

Only later did I understand this pattern: a rise of over 30%, followed by sideways movement for 3 to 5 days, then a volume-driven drop of 15%—this is the market maker offloading. When this pattern repeats, I short. I’ve never suffered this loss again.

**Lesson 2: Sideways is Not a Bottom, It’s a Trap**

In 2019, holding mainstream coins sideways for two months. I thought it was an opportunity, added leverage to buy more. As a result, I was cut in half.

The key signals are: sideways for over 20 days, turnover rate below 2%, deviation from the 20-day moving average by more than 20%. When these three conditions occur simultaneously, it’s a sign of distribution, foolproof. Now, once the system triggers, I immediately reduce my position.

**Lesson 3: Bottom-Fishing by Volume, Not Price**

On March 12, 2020, when BTC crashed, I tried to bottom-fish a certain coin, but got trapped for a long time.

Later, I learned what a real bottom looks like: low-volume consolidation combined with three consecutive days of gentle volume increase with small bullish candles. Last year, BTC showed this pattern near 25,000 yuan. I went all-in, sold at 42,000 yuan, earning 5.8 million in a single trade.

**Lesson 4: The Only Way to Win Is to Survive**

In the crypto world, it’s not about who is the smartest, but who can stay alive.

I only use half my position, never leverage. Before entering, I look for volume at least five times higher. When the trend breaks, I take profits immediately. I earned 12 times on one coin, while avoiding subsequent crashes.

Market patterns change, but human nature never does. Stick to your bottom line, and you can go far.

I’m glad to share with everyone, and I hope these lessons can help you.
