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

Since entering the market in 2017, I have experienced the fanaticism of the 3 o'clock community, the sleepless night of "94", and various coins being bombarded in turn. From spot trading to futures, from small-cap coins to mainstream coins, I have 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 underlying strategies I’ve summarized with real money—"Break the line and exit" and "Step-by-step harvesting."

**Break the level and run, don’t fall in love with the market**

My first strict rule: any coin that falls below the 70-day moving average, regardless of unrealized profit or loss, must be sold 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 moving average, it usually indicates that the medium-term capital consensus is loosening, and the risk of trend reversal is high.

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

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

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—don’t be fooled by intraday fluctuations. Second, act decisively; once the level is broken, don’t fantasize—execute immediately. Selling wrong is always better than being trapped.
