Common trading pairs include BTC/USDT, ETH/USDT, BNB/USDT, etc. These pairs usually have high liquidity, low slippage, and quick transactions, making them suitable for beginners.

There are also some smaller coin trading pairs like DOGE/USDT and PEPE/USDT, which, while highly volatile, also come with high risks.
