Yes, you can trade any token in a USDT pair, except for BTC/USDT. This is because USDT is a stablecoin, meaning it is pegged to the US Dollar and is designed to maintain a consistent value. BTC/USDT, on the other hand, is a crypto-to-crypto pair and is subject to the market forces of supply and demand. Trading tokens in a USDT pair is a great way to protect your capital from the volatility of the crypto market.
