$BTC

A BTC coin pair refers to a trading pair where Bitcoin (BTC) is used as the base currency against another cryptocurrency. In crypto exchanges, traders use BTC pairs to measure the value of altcoins relative to Bitcoin. For example, in the ETH/BTC pair, Ethereum's price is quoted in BTC. BTC pairs are popular because Bitcoin is the most liquid and widely accepted cryptocurrency. They allow users to diversify holdings, analyze market trends, and execute trades without converting to fiat. BTC pairs also help gauge an altcoin’s performance relative to Bitcoin, offering insights into broader market sentiment and potential investment opportunities.
