What is Binance Coin?
Binance Coin logo
Binance Coin is the official cryptocurrency of the Binance exchange, which allows holders to receive a discount on their Binance trading fees. BNB also powers the Binance DEX (decentralized exchange).
Binance holds a 'burn' every three months which removes a number of BNB coins from the circulating supply. The amount of coins that Binance burns is based on the number of trades of the exchange over three months.
