#密码资产动态追踪 I was jolted awake by an urgent phone call in the early morning hours — a trader from Zhejiang sobbing as they told their story: 5000U gone from their account, a full position with 5x leverage, liquidated completely after just a 3-point pullback.

This kind of story plays out in the crypto space every single day. How many people burn the midnight oil researching price movements and stacking indicators, only to be wiped out by those four words: "full leverage."

Trading the same derivatives contract, why do some traders grow their accounts steadily while others get zeroed out in an instant? The key isn't how precise your technical analysis is, but rather two of the most fundamental principles: position sizing and stop-loss execution.

The three most effective iron rules are actually quite simple:

**First Rule: Single position never exceeds 7% of total capital**
For a 5000U account, that means max 500U per trade. Even if you hit your stop loss, the damage is negligible and won't threaten your account's lifeline. $BTC $ETH

**Second Rule: Set single trade losses at 1.1% of total capital or less**
For example, a 500U position at 5x leverage with a stop loss set at 1%, keeps actual losses around 8.9U. When the stop triggers, let it. Don't give deepening losses any chance.

**Third Rule: Stay out of the market when you can't read it clearly**
This one's the hardest to follow. Don't add to existing profits, only enter when the trend is confirmed — like a daily timeframe breakout of key support with volume confirmation. Only then does the signal count.

One follower used to blow accounts repeatedly. After applying this system, they turned 3000U into 500k in 4 months. Steady and consistent always goes further than gambler's mentality.

The derivatives market will always be there. No need to rush.
