At 1 a.m., the phone screen flickered. It was Lao Chen's voice, a bit hoarse: "Bro, I lost another 800 bucks. I've stopped out three times this week. This 5,000 yuan is my wedding fund, I really don't know what to do anymore."

I didn't immediately advise him, but instead asked, "Are you trying to keep gambling on luck, or spend half a year learning a truly usable trading strategy?"

He immediately replied, "The latter must be the case."

Six months have passed. His account grew from 5,000 USD to 120,000 USD, all without a single liquidation. Not only did he recover all his losses, but he also held a decent wedding.

I've seen many stories like this over the years. After so much market analysis, what I want to emphasize isn't which coin will multiply tenfold, but a trading method that can truly sustain itself.

**Capital allocation is the first line of defense**

Lao Chen's biggest flaw is a typical crypto disease: full-position all-in, blindly trading based on emotions. This is the starting point for most people's losses.

I restructured his portfolio. The 5,000 yuan was divided into three parts.

Day trading account with 3,000 yuan, focusing only on BTC and ETH, with a 2% fluctuation trigger for take profit. Sounds conservative, right? But the actual results were surprising. Most of the time, the crypto market just oscillates there, and small, frequent profits accumulate, which is far more reliable than chasing those "penny coins" with wild surges and drops.

Rules are more reliable than luck, and systems go further than intuition. This is something I’ve realized after so many years.
