That cracked screen phone, with its web-like fracture, has been lying at the bottom of my drawer. The moment 360,000 yuan vanished in a bad decision, I didn't hear a trading alert tone, but rather the sound of a complete collapse of my inner defenses—my last bit of obsession with "getting rich overnight" was shattered completely.

In the following three days, I locked myself in my room. Only the rustling of pages and the cold glow of the screen kept me company. When spring came and I met with friends, I threw my phone on the table: not only did I fill the 360,000 yuan loss gap in my account, but I also earned a profit of 30,000 yuan. Having been in the crypto market for six years, I understand better than anyone—there's no luck behind this comeback, only three survival rules taught to me through blood and tears.

**Rule 1: Never go all-in, leave yourself a way out**

I used to be a firm believer in full position trading, thinking that going all-in was the real show of courage. How did that 360,000 yuan disappear? It was chasing a coin touted as a "dark horse" in chain gaming, only for the project team to secretly dump the coin, halving the value for three consecutive days.

Now, my position allocation is simple and straightforward:

Core holdings (50%): Only buy assets like BTC and ETH—"Yao Ming-level" assets. They may not be the fastest to rise, but they don't fall deeply and tend to rise steadily.

Flexible holdings (25%): Reserve for high-growth coins with a story, like Solana, BNB.

Cash holdings (25%): Half in stablecoins, half in fiat currency. During market crashes, this is real money for bottom-fishing.

The key is: never invest more than a quarter of your total funds in a single trade. Missing out on a hundred rallies is better than getting wiped out once.

**Rule 2: Stop-loss is like a broken arrow—cutting losses hurts, but it can save your life**

I have a note stuck on my computer—just four simple words.
