$BTC A BTC coin pair refers to a trading pair on crypto exchanges where Bitcoin (BTC) is traded against another cryptocurrency. For example, in the ETH/BTC pair, you trade Ethereum for Bitcoin and vice versa. BTC pairs are widely used to measure a coin’s strength relative to Bitcoin, not fiat currencies. These pairs help traders identify market trends, make arbitrage plays, and diversify portfolios. BTC is often a base currency due to its liquidity and dominance. Monitoring BTC coin pairs allows traders to spot altcoin breakouts or Bitcoin dominance shifts, making them essential tools in advanced crypto trading strategies.
