#比特币与黄金战争 $ETH suddenly crashed in the early morning, triggering an emergency call.

On the other end was a female trader from Jiangsu, her voice trembling—her account was gone. $6,000 of principal, 5x leverage, full position—just a 3-point adjustment and she was liquidated. Looking at her trading record, she had all $5,800 pressed in, and didn’t even set a stop-loss.

$BTC markets are daily scenes like this. Most people believe that full position can accelerate profits, but they don’t realize it’s like driving a car without a braking system—tilt the steering wheel slightly, and you plunge into the abyss instantly.

**The real reason for liquidation is often not the leverage multiple, but the position size ratio.**

Numbers tell the story. An $800 account using $750 to go long with 5x leverage will be completely out with just a 6% adverse move. But if you only use $75 for the same 5x operation, it takes an 86.7% adverse move to wipe out the principal. The difference? Nearly 12 times the defensive capacity.

That female trader committed 96.7% of her total funds. With 5x leverage, even a slight pullback is enough to be fatal.

Over the past year, I’ve encountered countless pitfalls, and I’ve summarized three survival rules—ensuring not only the safety of the principal but also an approximately 80% account growth:

**Rule 1: Use only 7% of total funds for each trade.** For example, with a $6,000 account, a single trade should max out at $420. Even if a 7% stop-loss is triggered, the actual loss is only $29.4, causing no major damage.

**Rule 2: No single loss should exceed 1.1% of total funds.** Using $420 for 5x leverage, setting a 1% stop-loss in advance, results in a theoretical loss of about $8.4, exactly 1.1% of the total funds. When pain points appear, exit immediately.

**Rule 3: Stay out of the market when the trend is unclear.** Reject the temptation to add positions; only trade when the trend is clear, the daily chart breaks key levels, and volume confirms the move.

I have a follower who used to blow up his account every month. After adopting this approach, he grew from $3,200 to $55,000 in four months. He told me something I remember well: "I used to think full position was gambling with my life. Now I realize, the real skill in full position is just surviving long enough."

The abyss is always open. I only keep one lamp lit—whether you want to come out alive depends entirely on your own choice.
