$BTC A coin pair with BTC, like ETH/BTC or SOL/BTC, lets you trade another cryptocurrency directly against Bitcoin. In this pair, BTC is the quote currency, and the other coin is the base. For example, in ETH/BTC, you're buying or selling Ethereum using Bitcoin. These pairs are useful for measuring how a coin performs compared to Bitcoin instead of fiat money. Traders often use BTC pairs to grow their Bitcoin holdings or diversify their crypto portfolio. Since both assets can be volatile, it’s important to manage risk carefully. BTC pairs are popular on major exchanges and among experienced traders.
