Exchange coins, or exchange tokens, are cryptocurrencies issued by crypto exchanges to serve various utility functions within their ecosystems. These coins offer users benefits like trading fee discounts, staking rewards, and access to special features or services. For instance, BNB offers reduced trading fees on Binance, and users can stake their coins to earn rewards or participate in exchange activities. Exchange coins can also be used for other purposes, such as collateral for loans or cross-platform transactions. The utility and benefits of these coins have led to their increasing popularity among crypto investors.
