At 3 a.m., I received a voice message from a friend, his voice full of helplessness. He said he had put all 10,000 yuan into a position, opened a 20x leverage order, and when the market only retraced 5%, his account was wiped out.

After reviewing his trading records, the problem was obvious: full position, high leverage, no stop-loss. This combination is like a ticking time bomb.

But here’s a point many traders get wrong—the real culprit behind liquidation is not the leverage multiple, but the size of the position.

**Why do full positions lose the worst?**

Let’s do a calculation with 1000 yuan: if you use 900 yuan to open a 10x position, a 5% market move against you will wipe out the account. But if you only use 100 yuan to open the same 10x position, it takes a 50% move against you to get liquidated. The numbers brutally demonstrate a fact—what determines life or death is never how many times your leverage is, but how much real money you put on the line in that trade.

My friend’s problem was putting 95% of his funds into one position at once. That’s not trading; that’s gambling.

**My three ironclad rules for half a year of full-position trading without liquidation**

**Rule 1: Single position ≤ 20% of total funds**

With 10,000 yuan in the account, the maximum single position is 2,000 yuan. Set a 10% stop-loss, and in the worst case, only lose 200 yuan. The account remains alive and can continue to participate in the next opportunity.

**Rule 2: Single loss does not exceed 3% of total funds**

This enforces the stop-loss. If wrong, exit immediately. Even if mistakes happen repeatedly, the foundation remains intact. Many people are reluctant to take that small loss, but that small loss prevents big losses.

**Rule 3: Don’t open new positions during market consolidation, don’t add to winning positions**

Only trade clear trend breakouts. Don’t trade based on feelings, and don’t add to positions that are already profitable. Discipline is more valuable than intelligence.

**The true meaning of full position**

Many misunderstand this. Full position is not about fighting the market desperately; it’s about reserving enough margin for the account to have tolerance. The premise is light positions combined with strict risk control.

An experienced trader follows these three rules. In three months, he grew his account from 5,000 to 80,000 yuan. His insight is very practical: "I used to think full position meant gambling recklessly, but I later realized it’s about surviving longer."

In the crypto world, it’s not about who makes money fast, but who stays in the game. Less guessing of the market direction, more managing your positions. It may seem slower, but it allows you to go further.

The market is always there, but opportunities only come to those who survive.
