$BTC A **BTC coin pair** refers to a trading pair on cryptocurrency exchanges where Bitcoin (BTC) is paired with another cryptocurrency or fiat currency. For example, BTC/USD pairs Bitcoin with the US dollar, while BTC/ETH pairs it with Ethereum. These pairs allow traders to buy, sell, or exchange Bitcoin relative to another asset.

BTC pairs are among the most popular in the crypto market due to Bitcoin's dominance and liquidity. They serve as a benchmark for the broader market, often influencing the price movements of other cryptocurrencies. Traders use BTC pairs to speculate on price changes, hedge against volatility, or diversify their portfolios.

In addition to fiat pairs like BTC/USD or BTC/EUR, many altcoins are primarily traded against BTC (e.g., BTC/ETH or BTC/LTC). This reflects Bitcoin's role as a foundational asset in the crypto ecosystem. Exchanges often list hundreds of BTC pairs, making it a central hub for trading activity.
