USDT is a stablecoin that is pegged to the US dollar, meaning that there is an equivalent amount of US dollars held in reserve for each USDT token in circulation. 

You can use USDT to earn passive income through Bybit’s lending programs, or you can trade it on the platform. Bybit also offers USDT Perpetual Contracts, which are linear contracts that allow traders to place long or short contracts with no expiration date.
