I have been in the crypto circle for ten years, from the little novice who had a numb scalp when he looked at the K-line, to now I can calmly watch the account numbers jump up and down, and the tuition fees paid in the middle are not millions. What I want to talk about today is not the secrets of getting rich, but those living experiences that have been exchanged for real money.

**The principal is really gone if you lose it**

When I first entered the circle, I also fantasized about a stud to achieve financial freedom. The result? On the night of the LUNA crash in 2022, my brother's account bottomed out directly because he was full of leverage. I only took 10% of the position to test the waters, although it hurt, but at least it didn't hurt the foundation. Looking back now, the first rule of survival in the currency circle is always that living is more important than winning. Those who shouted "turn over" ended up mostly queuing up on the rooftop.

I remember a project that pulled 20 times in a week. Watching the account numbers soar, greed came on the top - "Wait a little longer, maybe it can be doubled". As a result, as soon as the regulatory news came out, all the profits were spit back, not to mention, and the principal was lost. After that time, I understood that I only eat the middle part of fish. Earn the desired goal? Leave. Don't always think about selling at the highest point, that's the work of the gods.

**Emotions are the most expensive luxury**

The strangest law in the currency circle: it will fly as soon as you cut the meat, and it will pierce the center of the earth as soon as you carry it to death. Last year, a certain MEME coin plummeted, and I stared at the disk with sweat in my palms, but the stop loss line had already been set - trigger and go, without hesitation. Then the coin fell by 90%, and I was glad I wasn't soft-hearted.

Many people say that "you can make a lot of money if you can hold it", but there is a premise: you can clearly distinguish what is a value pullback and what is a death spiral. The time ETH was cut in half from the high, I increased my position because the fundamentals did not change. But those Aircoin flash crashes? Stop loss immediately, don't wait a second.

**Less hands, more brain**

Someone posts screenshots of "lying down and making millions" every day on Twitter, if you really believe it, you will lose. The four letters DYOR (Do Your Own Research) are the lessons of blood and tears piled up from countless stories of liquidation. When others call for orders, you have to ask yourself: What problem does this project solve? Is the team reliable? Are there any pitfalls in the tokenomics model?

I now have a habit of getting some sleep before making any investment decisions. Impulse is the devil, especially when you see the words "double for a limited time". Projects that make you FOMO are often well-designed traps. 10% of the position trial and error is always better than a full position gamble.

In the final analysis, the currency circle is not a battlefield where you live and die, but a super long marathon. Those who run fast may not be able to make it to the finish line, and those who survive are qualified to talk and laugh. The core of the experience gained from millions of tuition fees is one sentence: revere the market, control desires, and keep the principal.
