At 3 a.m., a friend's desperate call came in. He used 10,000 USDT to open a full position with 20x leverage, and when the price only retraced 5%, he got liquidated — his account was wiped out.

I checked his position history, and the problem was obvious: full position opening, high leverage, no stop-loss set. Many novice traders have fallen into this trap, thinking that full position trading can "stabilize market fluctuations," but in reality, it leads to faster losses than isolated positions.

**Why is full position liquidation so easy? The real culprit isn't the leverage multiplier**

Here's an example. In an account with 1,000 USDT:
- Using 900 USDT to open a 10x leverage position, a mere 5% adverse move will directly liquidate
- Using 100 USDT to open a 10x leverage position, it takes a 50% adverse move to get liquidated

With the same leverage, different account sizes mean vastly different risks of liquidation. My friend put 95% of his principal into one position; a small retracement triggered liquidation. The larger the position, the less room for error — this is the fundamental reason for full position liquidation.

**Stick to 3 principles, and I’ve been using full positions for half a year without liquidation**

First: No single position should exceed 20% of the total account funds. For example, with a 10,000 USDT account, invest at most 2,000 USDT in one trade. Even if you get the direction wrong and set a 10% stop-loss, you only lose 200 USDT, leaving the principal intact and still having a chance to rebound.

Second: Never risk more than 3% of the total position on a single stop-loss. Taking a 2,000 USDT position with 10x leverage as an example, set a 1.5% stop-loss in advance, which results in a 300 USDT loss, exactly 3% of the total funds. Even a few wrong trades won't hurt your core capital.

Third: Avoid opening positions in choppy markets; never chase profits by buying high. Only trade in clear trending breakouts, and stay on the sidelines during sideways consolidation, no matter how tempting. Once you open a position, strictly follow your plan and don't let emotions lead you to add more.

**The correct way to use full positions: It’s a buffer, not a gambling tool**

The original purpose of the full position mode is to leave room for market fluctuations, but this requires light initial sizing and strict risk control.

There’s a follower who was always on the brink of liquidation. After applying these three principles, he turned 5,000 USDT into 80,000 USDT in three months. He told me something that left a deep impression: "I used to think full position was gambling my life, but now I realize it’s about staying safe."

The real secret in crypto is not who makes the most money quickly, but who survives the longest. Avoid betting on market direction; focus on position management. Slow growth is actually the fastest way.

Survival is more valuable than getting rich overnight. Are you ready to change your mindset?
