In this market, if you live long enough, you'll realize a harsh truth: most people don't fail because of their choices, but because of their mindset. I've seen countless newcomers rushing in with small capital, all dreaming of overnight riches, only to chase the highs and sell the lows, leverage heavily, and end up with zero in their accounts. Today, I want to share what I've learned over the years—nothing fancy, just four words: Discipline is greater than talent.

**The first key: Don't rely on "news" to choose coins**

Many people are captivated by "insider information" or a big trader’s calls. What I want to say is that those are just scythes cutting the grass. Instead of chasing rumors, focus on technical analysis. My only rule for selecting coins is this: only consider MACD bullish crossovers above the zero line.

Why be so strict? Because a bullish crossover above the zero line isn't just an ordinary signal; it indicates that the trend is officially shifting from weak to strong. Entering the market at this point helps filter out a lot of false signals. For example, during last year's rally, coins like SOL and AVAX completed their second bullish crossover above zero, and afterward, they experienced decent gains.

The key is not to be greedy. Focus on just 1 or 2 mainstream coins—BTC, ETH, SOL—these are enough to keep you busy. Trying to chase multiple coins at once often results in missing all of them.

**The second key: The 20-day moving average is a life-and-death line**

Many think moving averages are for beginners; experts look down on them. My real experience tells me this idea is completely wrong. The 20-day moving average is surprisingly useful the more I use it. My simple and straightforward rule is: if the price stays firmly above the 20-day MA, hold tight and don’t move. Once it breaks below? Exit immediately, no questions asked.

The most dangerous thought is "what if it bounces back?" The market hates luck-based thinking. That hesitation can wipe out all your profits for the month. I have a follower who learned trading from me but was terrible at holding positions—always sold early, giving away potential gains. Later, I advised him to set the 20-day MA as his phone wallpaper, so he would hold on online and cut losses offline. After doing this, his account grew significantly over six months—it's a completely different story now.

**What happens to those who stick to this method**

Ultimately, making money isn’t about being smarter; it’s about self-discipline. Disciplined, straightforward operations often beat clever but undisciplined decisions. I’ve seen too many people in this market repeatedly break their rules with "this time will be different," only to pay the price each time.

Conversely, those who truly live comfortably in this market almost always share one secret—discipline. They’re not necessarily better at predicting; their execution is impeccable.
