A coin pair with $ETH (Ethereum) refers to a trading pair on a cryptocurrency exchange where Ethereum is one of the two assets. For example, ETH/BTC means Ethereum is being traded against Bitcoin. Traders use these pairs to buy or sell ETH in exchange for another cryptocurrency or fiat currency, like ETH/USDT (Ethereum to Tether). The value of ETH in the pair reflects the market price relative to the other asset. ETH trading pairs are among the most popular due to Ethereum’s liquidity and utility. They allow users to engage in arbitrage, hedge positions, or gain exposure to market movements.
