On the day my sister lost 360,000 and was left with 3,600, I almost threw her phone into the hot pot—she was squatting on the balcony fighting with the trading software, her fingers poking the screen with a fierceness that was more intense than when she was cramming for college entrance exams. Finally, she slammed it down, the phone screen cracked like a spider web, and with red eyes, she shouted, 'It's all gone!'

For those three days, the low pressure at home could freeze boiling water, and the study door was locked tightly. I placed my meals at the door and could only hear the sound of her flipping through books inside. The person who used to laugh so hard it could shatter glass didn't even make a sound. At that time, I secretly resolved that when she came out, I would uninstall all the related software; whoever wants to stay in this broken market can do so.

As the Longjing tea in the spring tea house was just brewed, she suddenly invited me to meet. When she slammed her phone on the table, I was ready to comfort her—but the screen clearly showed a six-figure asset, not only filling the 360,000 hole but also making an additional 30,000. I almost spat my tea in her face: "What kind of divine technique did you steal?"

As a cryptocurrency analyst for 8 years, I have seen too many myths of overnight wealth and witnessed even more tragedies of losing everything. But my sister's comeback this time had no insider information and no luck; it was all about "the rules earned through losses"—this is precisely the core logic I want to emphasize to beginners: surviving in the crypto market is a thousand times more important than making quick money.

The first iron rule: Always leave an exit in your position; do not become a "fully invested gambler."

My sister used to be a typical "fully invested reckless trader"; as soon as the market showed signs of movement, she would go all in. When it went up, she would float around saying, "Let’s wait a bit longer, it can double," and when it went down, she pretended to be dead waiting for a rebound. The time she lost everything was when she fully invested in a hot spot, and the result was a 40% drop in three days, and by the time she wanted to cut losses, there was hardly any principal left.

When she turned things around, she set strict rules for herself: no single entry should exceed 25% of the total principal. At that time, I argued with her, saying it was too slow to make money; she rolled her eyes at me and retorted, "Slow is better than losing everything. Have you ever seen a naked swimmer still standing after the tide goes out?" Later, I saw her trading records, and even when she encountered particularly favorable market conditions, she invested at most 20%, and because her mindset was stable, she correctly timed several small waves.

The second iron rule: Never hesitate to stop losses; 10% is the final bottom line.

"Cut losses immediately at 10% floating loss," is a note my sister posted on her computer. Once, I observed her operation; as soon as she entered the market, it dropped by 8%. Before I could react, she had already clicked sell. I asked her what if it rebounded after stopping losses, and she pointed to the dying pothos on the balcony: "Just like this plant, if the roots rot and you don't cut them, the whole pot will die. A 10% floating loss is a signal of rotten roots; keep the principal, and you can enter again when the next opportunity arises."

This is also what I have always emphasized to my fans: stopping losses is not admitting defeat; it's buying insurance for the principal. How many people have turned small losses into big losses because of the lucky mindset of "just wait a bit longer," ultimately trapping their principal? My sister's lesson of 360,000 is essentially the cost of having a stop-loss line that is as good as non-existent.

The third iron rule: Profits must be cashed out; do not be blinded by numbers.

The most counterintuitive rule is this—after every profit, my sister only leaves 15% of the funds to continue trading, immediately transferring the rest to a safe account. Once she made over 6000 in a single day and immediately withdrew over 5000; I laughed at her for being "content with small profits," but she took out a calculator and explained, "Last time I lost 360,000 because I wanted to turn 50,000 into 100,000, and in the end, I lost both principal and interest. The numbers on the screen are virtual; cashing out is real money."

To be honest, I have seen too many "gamblers" in the crypto market: fully invested, chasing highs, not stopping losses, and floating when making money. But my sister's experience proves that there is never an "absolute dead end" in this market, only "people who do not follow the rules." Later, she helped a friend turn over 2000 in principal to nearly 10,000, relying on these three rules—there are no shortcuts, only respect for the market.

If you are also struggling in the crypto market, constantly cycling between "making quick money" and "losing big money," following me is definitely the right choice. Next time, I'll share those "lessons learned through tears" on avoiding pitfalls, after all, my sister's broken phone screen and the hot pot we never had are not for nothing.~#加密市场观察
