$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance ecosystem, originally launched in 2017 as an ERC-20 token on the Ethereum blockchain before migrating to Binance Chain. It is widely used to pay for transaction fees on Binance Exchange, access token sales, and participate in Binance Smart Chain (BSC) applications, including DeFi, NFTs, and gaming. BNB offers benefits such as trading fee discounts and is also used for payments, staking, and governance within the Binance ecosystem. With a fixed total supply of 200 million tokens, Binance periodically burns BNB to reduce supply and increase its value.
