How long can the crypto circle survive? Essentially, it's not about the speed of making money, but about the wisdom to stay alive.

Emergency calls at 2 a.m. are very common. A friend’s voice was panicked: "I opened a 10x position with 10,000 USDT in full margin, and it only dropped 3%, so why did my account get liquidated?" Looking at the trading record, he directly put in 9,500 USDT without setting a stop-loss. This kind of operation is seen all too often in the crypto world.

Many people fall into this trap — mistakenly believing that "full margin = strong defense capability." In fact, this logic is completely backwards. Misusing full margin can lead to death much faster than you think.

**The root cause of liquidation in full margin isn’t leverage, but the position itself**

Similar stories happen every day. One set of data is shocking: during an 8% crash in Bitcoin, about 87% of forced liquidations involved traders using full margin. When prices fluctuate violently, positions are forcibly liquidated en masse, and accounts are wiped out instantly.

Full margin mode may seem like a safety net, but it’s actually a ticking time bomb. All available balance in the account turns into margin, giving a false sense of security. To put it into actual numbers:
- An account with 1,000 USDT, with 900 USDT used for 10x leverage, a 5% adverse move → immediate liquidation;
- But if only 100 USDT is used for 10x leverage, it takes a 50% move to trigger liquidation.

My friend put 95% of his principal into a position, used 10x leverage, and just a slight adjustment was enough to wipe him out completely.

**Three hard rules for doubling your account in half a year without liquidation**

The core lesson in crypto trading is risk management. In such a highly volatile market, preserving your principal is always the top priority.

**Rule 1: No single position exceeds 20% of total funds.** This is not conservative; it’s the survival baseline. Even if your judgment is completely wrong, a single loss remains within an acceptable range.

**Rule 2: Reasonably set stop-loss levels.** Don’t think "Will it rebound?" Just set the stop-loss when needed. Those with a good mindset tend to survive the longest.

**Rule 3: Distinguish between full margin and isolated margin scenarios.** Use isolated margin for testing small funds; consider full margin only for large, stable operations — but even then, strictly control the proportion of each position.

Those who have survived cycles, none of them won by gambling. They rely on calculating every trade carefully.
