#战略性加仓BTC Why do contracts always get liquidated? Honestly, it's not usually about choosing the wrong direction, but about not fully understanding these three hidden rules.

Some time ago, a friend of mine had the correct market outlook and held a short position for four days, but ended up losing 1000U due to funding fees, and was finally forced to liquidate. When the market truly takes off, all you can do is watch. It’s ridiculous.

**Trap 1: Funding fees secretly drain your funds**

Many people focus solely on candlestick charts but fail to realize that funding fees are settled every 8 hours. If the rate is positive? Congratulations, you’re paying every cycle. Going full margin long with the correct direction, but your margin is slowly being eaten away, and eventually you get liquidated.

How to avoid? Simple—control your holding time, ideally not exceeding 8 hours; if you must hold longer, choose a direction where funding fees are in your favor.

**Trap 2: The liquidation price is not the line you calculate**

Leverage of 10x crashing at 10% decline? That’s too simplistic. The platform also deducts fees when calculating liquidation prices, so the number you see is only theoretical. In reality, you’re gone at a 5% drop. Want proof? Try it yourself.

Solution: Don’t go full margin; use isolated margin mode, keep leverage between 3-5x, and reserve enough margin as a buffer. Leave yourself an escape route so the market doesn’t harvest you.

**Trap 3: High leverage is like wielding a sharp knife**

100x leverage sounds exciting, but the more borrowed money you use, the larger the absolute value of fees and funding costs. Even if your direction is correct, the costs can eat up all your profits.

Golden rule: Use high leverage for quick entries and exits; lower leverage allows for longer survival.

Profiting from contracts is never just about guessing the right direction. The key is understanding how exchanges make money. Every mechanism—funding fees, transaction fees, liquidation logic—is desig
