I mentored someone, turning 1,000 US dollars into 30k US dollars.

But in the end, I was the one who deleted him.

When he first came, he was very typical—following the group to chase low-quality coins, frequently going all-in, his account bouncing back and forth to zero.

I didn't teach him any complicated techniques, only three things for him to focus on first.

First, separate your funds.

Split 1,000 US dollars into three parts: one for short-term trades—one order per day; one waiting for opportunities—only act when conditions are right; and one as a safety net—never touch it.

Learn to survive first, then talk about making money.

Second, avoid trash markets.

Most of the time, the market is just oscillating, not worth trading. Wait for a clear trend before jumping in.

He later realized—doing nothing is much harder than acting recklessly.

Third, let rules make decisions for you.

Set stop-loss and take-profit levels in advance. Exit when you lose, take profits gradually when you gain.

Once he almost canceled his stop-loss, but when the market kept falling, he finally understood—stop-loss isn't about giving up, it's about protecting your life.

Gradually, he stabilized and reached over 30k US dollars.

But then the problem started.

He began to think he "understood," felt rules were too slow, started over-leveraging, chasing hot trends. Soon, his account was halved in drawdown.

That day, he told me: "If I had been braver back then, I would have made even more money by now."

Seeing that, I knew he had returned to square one.

Before deleting him, I only said one thing: The money you make is given to you by the rules. The money you lose later will only be what you take back yourself.

This market isn't short of opportunities, but it repeatedly eliminates those who don't follow the rules.

The ones who can take you far are never about how much you make in a few trades, but whether you can always stick to the simplest principles.
