I received an urgent call early in the morning. A trader from Jiangxi was very distressed: "I went all-in with 10,000 USDT at 10x leverage, and just a 3% pullback wiped out my account. How is that possible?"

Looking at his trading record, I saw he had gone all-in with 9,500 USDT without even setting a stop-loss.

Too many people interpret "full position" as "I can bear the maximum risk," but in reality, it's the exact opposite—using full leverage incorrectly leads to the fastest ruin.

**Position size is the real culprit behind liquidation**

For the same 1,000 USDT account:
- Using 900 USDT at 10x leverage, a 5% adverse move will wipe out the account
- Using 100 USDT at 10x leverage, it takes a 50% adverse move to get liquidated

That friend put 95% of his principal into one trade; a slight pullback and it was gone— the problem is never the leverage multiplier but the position size ratio.

**Three ironclad rules to keep full positions stable and growing**

1. No single position should exceed 20% of total funds

For a 10,000 USDT account, the maximum per trade is 2,000 USDT. Even with a 10% stop-loss, only 200 USDT is lost, leaving the principal intact and ready to adjust strategies at any time.

2. The maximum loss per trade is 3% of the total position

For example, with 2,000 USDT at 10x leverage, setting a 1.5% stop-loss results in a 300 USDT loss, which is exactly 3% of the total funds. Even a few consecutive wrong trades won't cause serious damage.

3. Do not trade sideways; do not add to profits

Only enter positions when a clear trend breaks out. During volatile sideways markets, stay on the sidelines; once in a position, strictly follow the plan without emotional interference.

**The true meaning of full position**

The essence of the full position mechanism is to reserve room for volatility, but only if combined with light position testing and strict risk control.

A follower once kept blowing up his account every month. After following these three rules, he managed to grow from 5,000 USDT to 8,000 USDT in three months. He later said, "I used to think full position was gambling my life, but now I understand—full position is about living more steadily."

In the crypto world, the competition isn't about who makes money faster, but who survives longer. Reduce overconfidence in directional judgment, increase reverence for position management—slow is the real fast.
