Holding just a few thousand yuan, the easiest mistake to make is greed. The crypto world is filled with stories of overnight riches, but in reality, most retail investors end up being slapped in the face by the market. Over more than ten years of trading experience, I’ve come to understand one principle: long-term profitability depends not on luck, nor on inside information, but on execution.

I’ve seen many people use "clumsy methods" to gradually grow their five-figure capital into seven figures. They don’t have any special talent; they simply stick firmly to these four ironclad rules.

**Rule 1: Choose coins based on MACD golden cross, only act above the zero line**

Don’t be led astray by the countless concepts and news flying around the market. The most reliable decisions come from technical analysis. A MACD golden cross appearing above the zero line is a solid entry signal. It won’t deceive you and is far more trustworthy than some influencers’ calls. Of course, this doesn’t mean a 100% success rate, but it generally points in the right direction.

**Rule 2: The 20-day moving average is the life-and-death line**

Hold firmly when the price is above this line; decisively exit when it drops below. No buts, no ifs, no waiting. Many people stumble here, always finding reasons to delay their decision. The value of discipline lies in this—when the market fluctuates, you don’t need to think; just look at the line.

**Rule 3: Enter only when volume and price break together; take profits step by step**

The entry condition is clear: price breaks above the moving average + volume expands simultaneously. This is when you can consider adding to your position. Exiting is even more particular—when the price rises 40%, take half profit; at 80%, take another portion; if it falls below the moving average, close all positions. Greed for that last point? Then prepare to get slapped in the face again.

**Rule 4: Close positions if the closing price breaks the line, must clear the position the next day**

This is a lifesaver. If the closing price falls below the 20-day moving average, no matter how the market performs the next day, you must exit. A lucky break could cost you months’ worth of profits. Missing out isn’t scary; the real opportunities come when the market stabilizes above the moving average. There are always chances, no need to rush.

This method may not sound exciting; it doesn’t offer big swings or quick thrills, but its strength lies in stability. During a certain mainstream coin rally, strictly following these rules allowed me to ride a beautiful upward trend smoothly. Many people later regretted "if only I had followed from the start," but when the opportunity was right in front of them, they didn’t execute. At that moment, information and connections can’t help.

If you’re still struggling with choosing coins, when to enter, and when to exit, consider printing out these four rules and sticking them on your screen. Stick to discipline. From a few thousand yuan to doubling your capital, or even more—this isn’t a dream, it’s a matter of probability.
