$USDC

In the crypto market, $USDT (Tether) is a popular stablecoin that is pegged to the US dollar. When a coin is paired with USDT, it means you can buy or sell that coin in exchange for USDT. This makes pair trading easier and lower risk since the value of USDT remains stable. For example, if BTC/USDT is the pair, you will trade Bitcoin for USDT. This system helps provide transparency, liquidity, and ease of pricing in the market.
