$BTC Bitcoin (BTC) remains the leading cryptocurrency and is often paired with a wide variety of altcoins across global exchanges. Trading BTC pairs allows investors to assess the value of other cryptocurrencies in terms of Bitcoin, rather than fiat currencies like the USD. This is especially useful in the crypto ecosystem, where BTC is often considered the benchmark. Common BTC pairs include ETH/BTC, XRP/BTC, and LTC/BTC. Traders monitor these pairs to identify relative strength or weakness between assets. BTC pair trading can also offer arbitrage opportunities, portfolio diversification, and a hedge against fiat volatility. As market conditions evolve, BTC remains a core pillar in crypto trading strategies.
