$XRP Coin pairs are the bedrock of cryptocurrency trading, acting as the bridge between different digital assets. In essence, a coin pair represents a trade between two cryptocurrencies, indicating how much of one (the quote currency) is needed to purchase a unit of the other (the base currency). For example, in the BTC/ETH pair, BTC is the base currency, and ETH is the quote currency. This means the pair shows how much ETH is required to buy one BTC.
