I saw a case yesterday that almost kept me awake—A guy from Jiangxi used 10,000 yuan of principal with leverage of over ten times. BTC only shook a few times, and his account was gone. Even more outrageous, this guy used 95% of his position as margin, and he never set a single stop-loss during the entire trading process. I was thinking at the time, this isn’t trading, it’s just burning paper money for the exchange.

Many beginners get scared when they hear "full position" and think it’s a gamble. But the problem isn’t with the full position itself, it’s how you use it. Using 90% of your capital to open a high leverage position, a 5% adverse move can wipe you out; on the other hand, using only 10% of your capital, the same market movement might require you to endure a 50% drawdown before liquidation. The key isn’t that the market doesn’t give opportunities, but that you haven’t learned how to manage your position.

I also participate in high-leverage trading, but I’ve set three strict rules for myself that I never break:

**Rule 1: No single trade exceeds 20% of capital**
With 10,000 yuan, I never risk more than 2,000 yuan. Assuming 10x leverage and a 10% stop-loss, the worst case is a 200 yuan loss. This way, I always keep the breathing room in my account, never getting wiped out by a single move.

**Rule 2: No single loss damages my core capital**
The 2,000 yuan position must have a stop-loss within 3% of my total funds. This means even if I hit a loss ten times in a row, I’ll only lose a small part, and my main account remains intact.

**Rule 3: Only trade when the trend is clear**
During sideways consolidation, I watch and don’t add small profits. Once I feel I’m getting too emotional, I just close the app and do something else. This is the most overlooked but most crucial rule.

I once mentored a friend who kept bouncing on the edge of liquidation every month. Later, following this logic, he turned 5,000 yuan into 30,000 in three months. He told me later that he finally understood what “full position isn’t about rushing to the top, but about putting on a bulletproof vest before going to battle.”

Ultimately, the ones who survive the longest in trading are never the boldest, but those who understand that “survive first, then make money.” Those who die quickly aren’t because the market is too fierce, but because they voluntarily walk into the trap of the market.
