📉💸 Let's talk margin! Isolated vs. Cross – a crucial lesson I learned. You have $1000. Open a $100 BTC long (10x leverage), initial margin $10.

**Isolated Margin** dedicates only $10 to that trade. If BTC tanks and your position liquidates, you lose *just* $10. Your remaining $990 is safe.

**Cross Margin** makes your *entire $1000 account* available as collateral. That $10 trade can pull from your whole balance to avoid liquidation, potentially wiping out your *entire $1000*. My $600 disaster? Cross margin.

My advice: New to futures? Use **Isolated Margin**; it caps losses per trade. Use **Cross Margin** only when you grasp portfolio-wide risk across multiple positions. Protect your capital!
