Many people lose money trading cryptocurrencies. On the surface, it seems to be choosing the wrong coins, but essentially, it's because they haven't established a systematic trading discipline. I've seen too many people rush in at the slightest market fluctuation, only to end up bankrupt. Actually, making money isn't that complicated; the key is to grasp a few core principles.

**Coin selection logic is straightforward:** Focus on the top gainers; coins that have already shown a trend are more likely to continue. Conversely, coins with no significant movement over a long period are often just throwing money away—don't waste your time.

**Time frame must match:** Candlestick charts are suitable for short-term rhythm, but to capture medium-term trends, the monthly MACD golden cross is the real signal. If there's no golden cross, stay out of the market and don't gamble recklessly. Many people fall into this trap—they always want to bet on oversold rebounds, but usually, they'll lose money.

**Specific operation route:** I pay close attention to the 60-day moving average. When the price pulls back near the 70-day moving average and volume increases, it's a clearer sign to add to your position. If you don't see this signal, keep waiting—no need to rush. After entering, either hold if it rises, or cut losses immediately if it breaks below the 70-day moving average. Many people are reluctant to sell, dragging profits into losses—that's extremely dangerous.

**Profit-taking rhythm is crucial:** When gains reach 30%, cut half of your position; when it reaches 50%, cut the remaining half. The market is active every day; missing this wave doesn't mean there won't be another. The main thing is to come out alive.

**The most important discipline is this:** If it breaks below the 70-day moving average, there's no room for negotiation—just exit immediately. No matter how long you've held or how optimistic you are about the future, this line is your life-saving charm. When trading in the crypto space, you must believe one thing: the simpler the rules, the more profitable. It relies on execution and emotional management, not on fantasizing about a quick turnaround.
