Last week I witnessed a miraculous case: a buddy who came to me three months ago complaining with just 3,000 yuan now has an account balance of 500,000. I still remember what he said to me: "I used to stay up all night staring at the charts, my eyes were almost blind, and the more I lost, the more I could only afford instant noodles; now I get a full 8 hours of sleep every night, and the money just grows by itself."

Having been in this market for 6 years, I can honestly say this from the bottom of my heart: when retail investors lose money, 9 out of 10 times it's not because of lack of skill, but because they lose to themselves. Those indicators that make you get up in the middle of the night to study K-lines, and those so-called "guaranteed profit" miracle strategies? They're just tools for cutting leeks. If you want to snowball small funds, you need to rely on three iron rules that go against human nature—today I'm sharing all my most valuable experience.

Let me first talk about how miserable this buddy was at the start. Last year, he bought high and got stuck, and after cutting losses, he was left with only 3,000 yuan in principal. He would ask in the group every day, "Any inside info?" and almost got scammed out of his last savings. I didn't recommend any coins to him at the time; I just told him three words: "Follow the rules." Now he tells everyone that these principles are more useful than any analyst's signals.

Rule #1: Be a hunter, not a gambler. Position sizing is your shield.

I've seen too many people treat the market like a casino. As soon as there's a little volatility, they go all in, shouting "bet big, small bike turns into a motorbike," but usually end up losing everything. My buddy was like this at first, thinking "with little money, you have to go big to turn things around." I shot back, "The less money you have, the more you need to cherish it. Position management is your shield."

The right approach is this: before the trend is clear, use at most 10-20% of your position to test the waters. It's like a hunter going on a hunt—throw a stone first to test the waters, and only go all in once you're sure it's safe.
