How to multiply profits when the price goes up?
Suppose that you have 2,000 USDT, you can use 10X leverage to buy 1 BTC in the BTCUSDT market.
When BTC price goes up to 25,000 USDT, your PNL is 1 * (25,000-20,000）= 5,000 USDT.
If you use 2,000 USDT to buy BTC in spot trading, you can only make a profit of 500 USDT. In futures trading, your profits are multiplied by 10 times with 10X leverage.
| Position Amount | Opening Price | Closing Price | PNL |
| 1 BTC | 20,000 USDT | 25,000 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 Contract 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.
