#数字资产市场观察 At three in the morning, looking at the initial amount of 4100U in the transaction records, I suddenly remembered my self from six years ago who almost jumped off a building.

That year, after the tenth liquidation, the 100,000 principal evaporated down to just enough for my underwear. Old Li poured me half a jin of white liquor at the dinner table and threw over three A4 sheets: "Follow this, and if you can't do it, roll back to the construction site and carry bricks."

**The first paper has only seven words: If you don't understand, then don't move.**

I used to be a typical retail investor—jumping on every coin that made it to the top ten on trending lists, buying whatever the community shouted about. The result? Every time, I was left standing at the peak. Old Li forced me to watch the K-line charts for a full two weeks, forbidding me from making any trades. Later, I developed a habit: I wouldn't touch my account balance until the trend had clearly emerged; once a breakout signal was confirmed, I would complete my position within three minutes. The first trade I executed based on this logic resulted in a direct gain of 78% in a swing.

**The second sheet of paper drew three kitchen knives**

Old Li forcibly divided the remaining money in my card into three parts:
Trial and Error Position (30%) - Used to test the waters, immediately back down if wrong.
Main position (50%) - Enter in batches after confirming the direction
Reserve Team (20%) - Reserved for Black Swans or Super Markets

I remember a time when a small cryptocurrency surged by 300% in a day, and I was itching to gamble all my remaining money. Old Li just pulled out my internet cable. Two weeks later, that cryptocurrency dropped back to a fraction of its original price, and I treated him to a hotpot.

**The third paper is the bank card number**

"Every time I earn 30 points, I immediately withdraw half to the cold wallet. If you dare to touch the money inside, I will break your legs." Old Li's rule sounds crude, but it is truly a protective charm. Floating profit is like mist; if you don't seize it, it will disperse. Only when I had saved up six figures in the cold wallet did I understand what it means to secure the gains."

Now living by Erhai Lake, I can make a maximum of five orders a month, and the earnings are enough to cover most workers' annual salaries. Occasionally, someone asks me how I do it, and I always think of those three crumpled A4 papers from Old Li.

In the cryptocurrency world, it is not the smartest who survive, but rather those who follow the rules.
