The biggest devil in trading is a lack of discipline.

I spent 8 years in the crypto market earning 15 million, and many people think it's luck. In fact, it's all experience gained through paying tuition. Every lesson learned from losing money becomes the capital for the next profit.

People often complain to me: "Bro, how do you choose coins? Why do I always get caught?" Basically, they haven't figured out the market's temperament. My approach is quite simple—just some fundamental rules. It may seem unimpressive, but these seemingly simple things are what helped me survive multiple bull and bear cycles.

Are you like this: as soon as the market moves, you can't sit still, rush in aggressively, only to end up trapped or wiped out? I've been there too; the moment my account shrank was truly worse than death. The 6 rules I share today are all earned through real experience.

**Rule 1: Follow activity, stay away from dead coins**

When choosing coins, I only look at the top gainers, selecting those with high attention and trading volume. A coin with popularity has room for future performance.

Coins that have been stagnant for a long time or haven't moved in years look cheap and tempting, but that's a trap. You might imagine you've picked up a bargain, but it might stay there forever. The most scarce resource in crypto is time. Instead of betting on obscure coins to rebound, it's better to follow the mainstream funds.

**Rule 2: Use the monthly chart to identify trends; daily charts are noise**

Retail traders obsess over hourly charts, those with a bit more experience look at daily charts, and truly consistent profit-makers focus on the monthly chart. I never get caught up in short-term fluctuations; my core method is to watch the monthly MACD—buy when there's a golden cross, stay out when there isn't.

It sounds simple, but executing it requires strong mental discipline. When others are chasing quick gains, you're waiting, and that patience can drive you crazy. But it is this waiting that protects my principal.
