A friend named Ah Lin started with only 100,000 yuan when he first entered the crypto world.

At that time, he spent every day hanging out in groups, following big V accounts, and studying various trading strategies. Everything from TianDiZhen, main force behavior analysis, emotional cycles... each one more incredible than the last. But what happened? The more he learned, the more confused he became, and his account kept growing red.

It wasn't until he suffered a major loss that he realized a painfully honest fact: the few trades that actually made him money were surprisingly simple in logic.

He began to reflect and finally set four "anti-human nature" iron rules for himself.

**Rule 1: Only look at charts, ignore news.** Focus on coins showing obvious strength on the daily chart, using MACD golden crosses as a filter, especially those with a golden cross above the zero line. The strength or weakness shown on the chart is always more honest than stories.

**Rule 2: Stick firmly to the moving average.** If the price stays above the moving average, keep holding; if it falls below, exit unconditionally on the second trading day. No hesitation, no gambling, no illusions.

**Rule 3: Position size should be incremental.** Only consider adding to your position when the trend is confirmed and volume supports it. Take profits in stages during each rally, avoid greed.

**Rule 4: The most difficult one—stop loss based on closing price.** Exit if the closing price falls below the daily moving average. No matter how many bullish voices there are, they won't change your execution.

This approach may not sound sophisticated, and it might even seem a bit stupid. But it's this "stupidity" that allowed Ah Lin to survive through several market cycles. No overnight riches, but steady survival.

The most practical thing for newcomers in the crypto space is never some advanced strategy, but a set of logic you can truly stick to and that won't kill you.

If you're still struggling with what coin to buy, when to enter, or when to exit, the problem might not be your skills but the lack of a systematic mindset that can genuinely reduce losses.
