My phone kept vibrating early in the morning, and all the voice messages were the same: "I used 5000U full position with 50x leverage to go long, just a 3% pullback and my account was gone... What's going on?" After checking the trading records, my blood pressure shot up—4750U all-in, with no stop-loss.

**The real culprit behind full-position liquidation: it's not the leverage multiple, but the heavy position size**
Stop blaming leverage. What’s the true cause? The position size is too exaggerated.
Taking a 1000U account as an example makes it very clear: opening with 10x leverage on 900U, just a 5% market reversal, and the account is wiped out; conversely, with 100U at 10x leverage, it takes a 50% market move against you to get liquidated.
That friend put 95% of his principal into one trade. Even with only 10x leverage, a slight market correction would wipe him out immediately. This isn’t a leverage problem; it’s a disaster of position allocation.

**Three ironclad rules: full position trading for half a year without liquidation can still double your money**
Full position trading isn’t impossible; the key is to follow a method. With these three rules, I’ve avoided countless deadly pitfalls:
**Control single trade size within 20% of total funds**— for a 10,000U account, invest no more than 2,000U. Even if you make a wrong call and exit with a 10% stop-loss, you only lose 200U, which is manageable, and you can recover at any time.
**Set the maximum loss per trade at 3% of total funds**— for example, with 2000U at 10x leverage, set a 1.5% stop-loss in advance, risking exactly 300U, which is 3% of total funds. Even if you make several mistakes, you won’t be wiped out and can still have the capital to bounce back.
**No trading during sideways markets, no chasing profits**— only open positions when the trend is clear; avoid trading in choppy markets no matter how tempting. After profits, never add to your position, eliminating emotional trading at critical moments.

**The true purpose of full position trading: leaving room for market fluctuations, not gambling with your life**
Many people treat full position as a "small bet for big gains," but its original intent is completely opposite—it’s to leave enough buffer for market volatility. The prerequisite for this buffer is always light position sizing, combined with strict risk control.
A friend once kept blowing up his account every month, losing month after month. After following these three rules, he steadily grew his 5000U account to 8000U in three months. He said himself: "I used to think full position was gambling my life, but now I realize, full position is actually about surviving steadily in this market."
In the volatile days of the crypto market, instead of chasing overnight riches, it’s better to master this risk management system. It may seem conservative, but it’s actually the true way to survive.
