A friend of mine who has been running a business for many years later coincidentally entered the crypto space. He didn't follow the trend and chase hot topics, but instead rooted himself and carefully studied trading logic. Now, his assets have reached eight figures, relying on a trading method that looks incredibly simple.

He often says that making money doesn't require stacking complicated technical indicators. The core is four steps: selecting coins, buying, position management, and selling. Each step has clear rules.

**How to find coins?**
Open the daily chart and focus only on the daily timeframe. Look for coins with MACD golden crosses, especially those where the cross appears above the zero line, as this yields the best results. This filtering increases the win rate of opportunities.

**When to buy?**
Switch to the daily chart and focus on a single moving average—the daily moving average. The logic is straightforward: hold when above the MA, exit when below. When the price breaks above the daily MA and volume confirms it is also above the MA, that’s the moment to build a full position.

**How to sell safely?**
This is where discipline is most needed. If the wave gains more than 40%, sell 1/3 of the position; if it reaches 80%, sell another 1/3; if it falls below the daily MA, clear out the remaining holdings. It sounds mechanical, but this mechanical approach is precisely a defense against emotional decision-making.

**What is the most critical point?**
Mindset. Once it falls below the daily MA, don’t wait, don’t gamble—exit everything immediately. Although the probability of a breakdown using this coin selection logic is very low, risk awareness must always be maintained. After selling, wait for it to rise back above the MA before re-entering calmly. Staying calm and keeping the method simple is the underlying logic behind his asset explosion.
