$BTC A coin pair in cryptocurrency trading refers to two currencies that are traded against each other. The BTC pair typically involves Bitcoin (BTC) and another currency, such as USD (BTC/USD), Ethereum (BTC/ETH), or Tether (BTC/USDT). When traders engage with a BTC pair, they are either buying Bitcoin using the other currency or selling it to receive the other currency. For example, in the BTC/USDT pair, if a trader buys, they’re spending USDT to acquire BTC; if they sell, they’re exchanging BTC for USDT. BTC pairs are among the most liquid and widely traded in the crypto market, acting as a base or quote currency in many exchanges. Understanding BTC pairs is essential for price speculation, arbitrage, and navigating the crypto market efficiently. They also serve as benchmarks for altcoin performance and often reflect broader market sentiment due to Bitcoin’s dominant market role.
