$BTC A BTC pair refers to a trading pair where Bitcoin (BTC) is paired with another cryptocurrency or asset. In these pairs, the price of the second asset is quoted in terms of Bitcoin. For example, a BTC/ETH pair means you are trading Ethereum (ETH) for Bitcoin (BTC). These pairs are common in cryptocurrency exchanges, allowing traders to speculate on the price movements between Bitcoin and other assets. Trading in BTC pairs is essential for those who want to stay within the Bitcoin ecosystem, without converting their holdings into fiat currency. They are often used for liquidity and trading efficiency.
