I have a friend who once ran a small convenience store business, and later switched to the crypto space. He is not impatient for quick profits; instead, he spends a lot of time studying market trends and trading logic. Now, his account size has reached eight figures, and his secret to success is actually quite simple—it's about mastering a systematic trading framework.

This methodology revolves around four core steps: selecting coins, buying, position management, and taking profits or cutting losses. Every detail is thoroughly considered.

**Coin Selection Stage** is particularly meticulous. Open the daily chart, focus on the daily timeframe, and look for MACD golden cross signals. Especially those that form above the zero line, which tend to be most effective. The assets filtered out this way usually perform more steadily afterward.

**Buying Logic** is straightforward. Switch to the daily chart, focus on a single moving average— the daily moving average. Hold above the moving average, and clear the position below it—that's the entire rule. Once the price breaks above the daily moving average with moderate volume increase, you can go all-in.

**Profit-taking and Cutting Losses** are divided into several nodes. When the gain reaches 40%, sell one-third of the position; when it expands to 80%, sell another third; finally, if the price falls below the daily moving average, close out the remaining position.

**The most critical point**—risk awareness must come first. If the price suddenly drops below the daily moving average the next day, you must exit immediately—don't hold onto false hopes. Although, according to this coin selection logic, the probability of falling below is quite low, markets can always surprise you. After selling, patiently wait for it to stabilize above the daily moving average again; re-entering at that time is no problem. This is not just a trading method but also a discipline.
