How to multiply profits when the price goes down?
Suppose that you have 2,000 USDT, you can use 10X leverage to sell 1 BTC in the BTCUSDT market.
When the BTC price goes down from 20,000 USDT to 15,000 USDT, your PNL is 1 * (20,000-15,000）= 5,000 USDT.
If you trade in spot markets, you cannot make profits from going short.
| Position Amount | Opening Price | Closing Price | PNL |
| 1 BTC | 20,000 USDT | 15,000 USDT | 5,000 USDT |
Note: To simplify the calculation, the above process ignores the calculation of premium, margin profit and loss, trading fees and funding fees.

Risk Reminder
Futures Trading not only allows you to magnify gains with fewer funds but can also saddle you with amplified losses when the market moves against you. Therefore, we strongly advise entry-level users NOT to use high leverage to avoid forced liquidation or even bankruptcy.
