In the early hours, news of liquidation once again spread through the crypto circle.

A friend called, nearly in tears: "I put all my 10,000 yuan into a 10x leverage long position, it only retraced 3%, and my account was wiped out. What happened?"

After reviewing the trading records, I understood—he entered full position at 9,500 yuan without setting any stop-loss. This isn't trading; it's just burning money directly.

Many people have a misconception that "full position" means "can withstand." In reality, it's quite the opposite—using full position incorrectly often leads to the fastest death.

**The core issue isn't leverage, but overly heavy positions.**

With the same 10x leverage, if you enter with 900 yuan, a 5% adverse move will liquidate your position; but if you only use 100 yuan, it takes a 50% move against you to wipe out the account. That's the difference in position size.

The friend's problem was exactly this—pushing 95% of the principal all at once, and when the market slightly retraced, the account instantly went to zero.

So remember this: **Position size is the line between life and death; leverage is just an amplifier.**

Those who truly survive and go all-in follow three ironclad rules:

**First, no single position exceeds 20% of total funds.** Even if wrong, it won't break you.

**Second, limit single-loss to within 3% of total capital.** Even repeated mistakes can be endured.

**Third, only follow the trend, avoid chasing highs, and don't hard-push in sideways markets.** Reduce unnecessary gambling.

The real meaning of full position is to leave room for market fluctuations, not a tool for gambling.

The crypto world has never been about who makes the most money fastest, but about who survives the longest. To avoid the nightmare of zeroing out overnight and to profit steadily amid volatility, the most important thing is a sense of rhythm—this is a thousand times more important than blindly rushing in.
