At 2 a.m., my phone buzzed nonstop. A friend from Jiangxi sent voice messages one after another, sounding very urgent: #数字资产市场动态 $BTC Why is the $ETH market so坑?

"I put 10,000 yuan of capital, went all-in with 10x leverage on a long position, and just a 3% dip wiped out my account. What's going on?"

I checked his trading orders—9500 yuan per trade, no stop-loss set.

This guy fell into a common trap: many think that using leverage with full position size can "handle it," but in reality, poor operation leads to the fastest death. The key isn’t the leverage multiple, but how heavy the position you’re pressing down is.

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

With the same 1000 yuan account, two different approaches are easy to compare:
- 900 yuan with 10x leverage, a 5% adverse move → account wiped out
- 100 yuan with 10x leverage, needs a 50% move to be liquidated

My friend essentially risked 95% of his assets, using 10x leverage—just a small pullback and it’s all gone. Logically, it’s completely backwards.

**I’ve doubled my capital with zero liquidations in half a year, relying on these 3 iron rules**

First: No single position exceeds 20% of the total account

For a 10,000 yuan account, at most 2,000 yuan per trade. If the direction is wrong, a 10% stop-loss only loses 200 yuan, which is almost no harm to the principal. The key is that even if you get it wrong several times, you can immediately turn around, keeping your mindset stable.

Second: Limit single-loss to 3% of the total account

For example, a 10x position of 2,000 yuan, with a pre-set 1.5% stop-loss, means a 300 yuan loss—exactly 3% of the total account. Even if you hit multiple stop-outs, your core capital remains intact.

Third: Avoid trading in choppy markets, don’t chase profits

Only trade breakout opportunities. Even if the market consolidates, you must endure it; don’t add to positions after opening. This is pure risk management—completely banishing emotions from the trading system.

**The purpose of full position is to allow for error, not gambling**

The design of the full position tool is to leave buffer zones for price fluctuations, but the premise must be: small trial-and-error + strict risk control.

I had a friend who tracked his trades and kept blowing up his account every month. After applying these three rules, he managed to grow from 5,000 to 8,000 in three months. He said himself: "I used to think that trading with full leverage was gambling for my life. Now I understand, the purpose of full position is to stay alive steadily."

In the crypto world, survival isn’t about who makes money fast, but who lasts longer. True winners are those who control risk well and keep a calm mindset.
