Woken up by a friend's voice message in the early morning, I instantly knew what had happened—8000U full margin with 10x leverage, just a 3% pullback, and the account declared bankruptcy. Looking through the trading records, I saw a all-in bet of 7600U, with not even the basic stop-loss set.

I've seen this happen many times. Many people confuse a concept, equating full margin with risk resistance, but in reality, it’s the exact opposite. Using the wrong full margin, you’ll die faster than with isolated margin.

To be honest, the key to full margin liquidation is never the leverage multiple, but rather the size of the position taken. For example: an 800U account using 700U to open with 10x leverage, a 5% adverse move will hit the bottom; alternatively, using only 100U to open the same 10x leverage, it would take a 50% move to trigger liquidation. The difference lies entirely in the size of the position. My buddy was wiped out because he committed 95% of his principal in one shot.

With these three principles, I have gone half a year without a full margin liquidation, and instead, my account doubled.

**Principle 1: Do not invest more than 20% of total funds in a single trade**
With a 10,000U capital, never invest more than 2,000U in one attempt. Even if you pick the wrong direction, a 10% stop-loss only loses 200U, leaving the core capital intact and ready to recover.

**Principle 2: Keep single-loss down to within 3% of total margin**
When using 10x leverage with 2,000U, set the stop-loss at 1.5%, risking exactly 300U, which is 3% of the total margin. Even several wrong trades won't wipe out the core funds.

**Principle 3: Do not trade during sideways markets, and do not add positions after profits**
Only participate in breakouts; even if the consolidation looks tempting, stay on the sidelines. Once you open a position, stick to your plan—never add funds temporarily, to prevent emotional interference with decision-making.

The true meaning of full margin is to leave room for volatility, with core logic being light position sizing combined with strict risk control. A follower of mine kept blowing up his account every month, but after strictly following these three principles for three months, his 5,000U grew to 8,000U. He told me that before, he thought full margin was gambling his life away, but now he realizes it’s actually about maintaining stability.

In the crypto world, survival isn’t about who earns the most, but who lasts the longest. Spend less time guessing the market direction, and more time managing your positions—paradoxically, slowing down makes you faster. The market is always there; master the rhythm, and come in steadily.
