When my brother found me for the first time, I was already down. The account only had 3000U left, down from over 60,000 in principal due to my own mismanagement. He said, "It can still be saved," but I could tell he was genuinely scared.

I asked him: "Do you want to keep gambling, or do you want to actually make money?"

He was silent for half a minute: "Bro, I want to turn things around. I don’t want to live that kind of anxious life anymore."

So I set him one basic rule:

Stop trading for a day and go over all the previous operations.

In less than half an hour, he blushed and said, "So the problem was all on me."

The next day, we redefined our strategy—what I often refer to as the rolling position system:

Single position should not exceed 30%

Take profits at 10%-15%

Cut losses at 3%-4%

Avoid ambiguous trends

At the time, he resisted, saying, "Bro, this is too strict, right?"

I said, "If you don’t hold yourself accountable, the market will do it for you."

The first two weeks were excruciating for him.

A few times when the market continued to rise, he regretted taking profits too early;

And he also felt he “missed out” when he cut losses too quickly.

But no matter how volatile his emotions were, he followed the rules.

By the third week, he suddenly messaged me: "Bro, today for the first time I feel like I’m not gambling but trading."

At that moment, I knew he had overcome the toughest hurdle—calming his mind.

Three months later, he sent me a picture:

9000U → 138,000U.

He wasn’t excited; he just sighed and said something very real:

"It wasn’t luck that saved me, it was discipline that saved me."

Many people ask me, what is the hardest thing in the crypto space?

It’s not charting, it’s not news, and it’s not talent.

The hardest part is sticking to your own rhythm and not being led by the market.

The core of the rolling position system is four points—simple, straightforward, but practical:

1️⃣ Positions must be flexible: single position 20%-30%, leave room for retreat.

2️⃣ Profits should be taken quickly: take profits at 10%-15%, cut losses at 3%-4%.

3️⃣ Follow trends, don’t predict: no bottom fishing, no top touching; wait for the direction to emerge before entering.

4️⃣ Review daily: find problems, adjust the rhythm, create a positive cycle.

Markets will change, people's hearts will waver, but discipline will never let down those who execute it.

As long as the method is right and the rhythm is steady, even small funds can roll out their own future.
