Simple rules are the hardest to follow. Against human nature, sticking to discipline is the only way to survive the longest.

Since entering the market in 2017, I have experienced the frenzy of the three o'clock community, the sleepless night of "94," and the barrage of various coins. From spot trading to futures, from small-cap coins to mainstream coins, I’ve paid a lot of tuition—at the worst, my account shrank by 90%.

Over the years, my biggest realization is actually very simple: surviving longer is truly more valuable than earning quickly. Today, I want to share two fundamental strategies I’ve summarized with real money—"Break the Line and Exit" and "Step-by-Step Harvest."

**Run when the level breaks, don’t fall in love with the market**

My first strict rule: once any coin drops below the 70-day moving average, regardless of unrealized gains or losses, clear the position immediately.

The 70-day line is my "life and death line" for medium-term trends. This line has saved me countless times. Moving averages essentially reflect market consensus heating up. Once the price falls below the 70-day line, it usually indicates that the medium-term capital consensus is loosening, and the risk of trend reversal is high.

To put it plainly, many people stumble here not because they lack technical knowledge, but because they always think "wait a bit longer, maybe it will rebound." Wishful thinking is more deadly than any indicator.

I have a painful lesson: once heavily invested in a certain Layer2 project, I didn’t sell when it was 40% in profit, and hesitated at a key support level, resulting in profits gradually disappearing, and finally ending up with a 30% loss. Conversely, in May this year, I sold a very popular meme coin without hesitation when it broke below the 70-day line, and it later fell over 50%.

There are two core points to executing this strategy:

First, the standard must be objective—use the closing price to effectively break below the 70-day moving average as a hard indicator, don’t be fooled by intraday fluctuations. Second, act decisively—once the level breaks, don’t hesitate, execute immediately. It’s always better to sell wrong than to get trapped.
