$BTC A coin pair with BTC (Bitcoin) refers to a trading pair where Bitcoin is used as the base or quote currency against another cryptocurrency. In crypto trading, coin pairs like ETH/BTC or ADA/BTC allow users to exchange Ethereum or Cardano directly with Bitcoin without converting to fiat currency. BTC-based pairs are commonly used on major crypto exchanges because Bitcoin is the most dominant and widely accepted cryptocurrency. Trading with BTC pairs helps investors diversify portfolios, take advantage of market opportunities, and manage risks more efficiently. Understanding BTC pairs is essential for anyone involved in active cryptocurrency trading or investment strategies.
