Last year, a friend switched careers and entered the crypto space, using 50,000 yuan as startup capital. I shared with him the core logic of my three-year trading summary. When he later sent me his trading results, I realized that this methodology is indeed worth documenting.

**Level One: The Three Thresholds for Filtering Coins**

He initially focused on 20 popular coins. I told him to start with the weekly chart. Coins that have been in a continuous decline for more than 4 days are immediately excluded — it’s not about talent, but about trend. After this step, only 8 coins remain.

Next, look at the details. For example, a coin suddenly surges 25% in a single day — sounds tempting, but the funds quietly flowed out in the first three days, and the K-line shows a "sharp top" pattern — a typical main force distribution tactic. I pointed to the volume and said, “A rapid rise without volume is just a false alarm, avoid it.”

The final step is the strictest: the monthly MACD must be a golden cross, and the energy bars should be continuously turning red. Once this filter is applied, only 3 coins remain out of the original 20.

How did these 3 coins perform later? All of them surged over 180%. When he first sent a red envelope, he commented: “This is incredible.”

**Level Two: Buying Points Are Not Guesswork**

I repeatedly emphasize a principle: good opportunities are waited for, not chased.

On the daily chart, wait for the coin price to retest the 50-day moving average, while trading volume suddenly increases to more than three times the recent average — this is the real entry signal. No need to guess the bottom; the market’s volume will tell you the truth.

Take MATIC as an example. When it hits a key support level, the volume suddenly spikes — a clear signal. He planned to build positions in three batches:

Sell 1/3 when earning 20%, recover the initial principal, and the psychological burden instantly disappears; sell another 1/3 when earning 40%, locking in profits; use the remaining position to ride the trend.

With this rhythm, even if there’s a pullback later, the principal is protected, and the mindset remains very stable. Many people lose money in crypto not because they pick the wrong coins, but because they can’t control their emotions — a dip causes them to sell everything.

Finally, I want to say: opportunities in the crypto space are always there, but the only logical way to survive and make money is — choose the right direction, control the pace, and let time work for compound interest.
