Having traded for eight years, my principal has multiplied many times. It sounds respectable, but what is the behind-the-scenes effort? Countless lessons from stop-losses, margin calls, and missing market opportunities.

Some friends ask me if there are any secrets to choosing coins and making trades. Honestly, there are no secrets—methods are simple, but most people simply can't stick to them.

The most common way to fail is like this: seeing the market fluctuate wildly, unable to resist jumping in "for a quick move." The result is a margin call. I used to do this in my early years, and now looking back, I just find it ridiculous.

**Logic for Choosing Coins**

The top gainers are your spotlight. Why? Because only coins that have surged have market heat and real opportunities. Coins that remain stagnant are a waste of time no matter how long you watch.

Don’t obsess over minute or hourly charts. The golden cross on the monthly MACD is the real entry signal. If you don’t see the golden cross, stay out of the market. This isn’t conservatism; it’s probability theory—big opportunities are in long-term trends. Betting on oversold rebounds repeatedly will just wipe out your funds.

**Key Levels Must Not Be Ignored**

The 60-day moving average is a critical threshold. If the price retraces to near the 70-day moving average with significantly increased volume, consider adding to your position. Don’t panic; the market will give repeated testing opportunities. When the signal appears, stay steady; if not, keep waiting. Patience is especially valuable in the crypto world.

**Discipline After Entry**

If it rises, hold. Once it breaks below a key level, sell without hesitation. Many people fail at this step—they keep hoping for a rebound, only to watch their profits turn into losses. This is a common scenario.

Profit-taking should also be disciplined. Take half profits at a 30% gain, and if it rises to 50%, take half again. The benefit of this approach is that if the market turns, you won’t lose everything. Missing one opportunity is okay; the crypto world never lacks chances.

**The Most Important Iron Rule**

If it breaks below the 70-day moving average, get out immediately. No matter how long you've held or how reluctant you are, act when the signal appears. This isn’t hesitation; it’s survival.

I’ve survived in the crypto space by following this rule. Don’t fight the trend; don’t gamble recklessly.

**Summary**

The real way to make money in crypto is always the simplest. Don’t think about turning everything around overnight or getting rich in a day—that’s movie plot. In reality, those who survive do so by consistently following discipline and controlling their emotions.

All these lessons are blood-earned. The crypto market won’t betray those who follow the rules, but it will definitely teach a harsh lesson to those who trade on gut feelings.
