#大户持仓动态 Why is contract trading prone to sudden crashes? Many people fall victim to invisible pitfalls — it's not that they took the wrong direction, but that they are being strangled alive by "hidden costs."

Today, let's break down three of the most overlooked deadly vulnerabilities:

**Funding Fees Are the Real Vampires**
You only focus on the candlestick charts, unaware that every 8 hours, money is silently deducted. When the rate is positive, longs pay shorts; when negative, the opposite. Holding a full position and stubbornly holding on? Even if you guessed the right direction, two days of funding fees can wipe out all your profits. When a liquidation finally happens, the market might surge the next day. That’s why so many people see the right trend but still lose money. How to avoid this? If the rate exceeds 0.1%, don’t rush to enter. Don’t hold positions indefinitely; it’s best to take profits within 8 hours or actively be the one paying the fee.

**Liquidation Price Is Closer Than You Think**
Think that a 10x leverage only liquidates at a 10% drop? That’s a huge misconception. The platform’s liquidation fee is a hidden knife; in reality, you’re gone at just a 5% decline. So don’t go all-in with full margin. Switch to isolated margin mode to separate risks, keep leverage between 3-5x, and leave more margin for breathing room.

**High Leverage Is Like a Freezer**
100x leverage looks exciting, but fees and funding costs are calculated on the borrowed principal. You might earn a few hundred bucks, but when settling, you could end up losing money. Use high leverage only for short-term spikes; for long-term holding, keep leverage low. The higher the multiple, the faster you die — that’s an iron law.

Exchanges aren’t afraid of your losses; they’re afraid you see through their tricks. To survive longer in the crypto world, it’s not about betting on the right direction, but truly understanding how these rules work.
