Having navigated the crypto market for 8 years, I have never chased after so-called "big shots' signals" nor touched any air coins. Without complicated trading techniques, I rely on a simple and straightforward principle of "not greedy, not impatient" to multiply my principal by nearly a hundred times.

Now at 38 years old, I am settled in Hangzhou. Life is truly comfortable—no need to go to a job, I can go anywhere I want, eat whatever I like. I own three properties: one for myself, one for family, and the last one generating cash flow through rent. Behind this seemingly relaxed life is the result of years of strictly following these four rules.

**Rule 1: Slow Rises and Small Dips ≠ Weakness; Rapid Rises and Drops Are Warnings**

If the market is gradually climbing and each correction stays within 10%, that’s usually a healthy trend. But if a coin suddenly surges over 20% and then immediately plunges, nine out of ten times it’s the main players "cutting the fast knife." Don’t be led by FOMO; observe calmly rather than rushing to follow the trend.

**Rule 2: The more aggressive the call for a coin, the further you should stay away**

Projects that shout every day in various groups "must hit 10x" or "missed out, kicking myself"—don’t even bother with their profit screenshots. Truly promising projects don’t need "brainwashing marketing" to attract investors. Hype and value often go in opposite directions; don’t let noise cloud your judgment.

**Rule 3: Only invest up to 30% of your principal**

Even if you’re very optimistic about a coin, invest at most 30% of your total assets. The remaining 70% is reserved for extreme market conditions. Someone fully invested only needs one big drop to be completely out. Staying alive and continuing to play is much more important than chasing quick profits.

**Rule 4: Take 50% profit off the table after making money**

The crypto market changes in an instant; today’s gains can turn into tomorrow’s losses. No matter how many times it has multiplied, first take half of the profit off the table, then continue trading with the rest. This is not conservatism; it’s rationality.

Looking back over these 8 years, my biggest takeaway isn’t how many times my assets multiplied, but that discipline and self-control are a hundred times more important than prediction skills. There are many opportunities in the crypto space, but those who make it to the end and profit are the ones who can be ruthless with themselves.
