Contracts are an upgrade to leverage, more user-friendly than leverage, without the need to borrow and return coins, and the operation is simple. You can operate as long as you have coins or USDT in your position.

Contracts are divided into two categories based on time:

One type is perpetual contracts, which means you can hold them for a long time as long as you don't get liquidated.

The other type has a time limit, divided into: this week, next week, and quarterly, which means they will automatically close positions when the time is up.

Contracts and leverage have two trading pairs: coin-to-coin and USDT. The former settles profits in coins, which we call coin-denominated, where profits are based on the increase in the number of coins, while USDT trading pairs settle in USDT.

Going long on coin-denominated contracts yields more profit than going long on USDT-denominated ones~
