$BTC

A coin pair with BTC (Bitcoin) refers to a trading pair on a crypto exchange where Bitcoin is used as either the base or quote currency. For example:

ETH/BTC: This pair lets you trade Ethereum (ETH) for Bitcoin (BTC), or vice versa.

BTC/USDT: One of the most popular pairs, this allows trading BTC against Tether (a stablecoin).

Why BTC pairs matter:

BTC is often used as a benchmark in the crypto world. Trading altcoins against BTC gives investors a way to measure performance relative to Bitcoin, not just fiat currency. It’s also useful when fiat trading is restricted, as BTC often acts as a bridge to access other cryptocurrencies.

In short, BTC pairs are central to the liquidity and pricing structure of most crypto markets.
