$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance ecosystem, originally launched in 2017 as an ERC-20 token on Ethereum before migrating to Binance’s own blockchain, BNB Chain. It is widely used for transaction fees on Binance, trading fee discounts, and various DeFi applications. BNB has expanded its utility beyond the Binance exchange, including payments, token sales, and smart contract functionality. With a deflationary model, Binance regularly burns a portion of BNB to reduce supply and maintain its value. Its integration into the Binance Smart Chain (BSC) has also fueled its adoption in decentralized finance (DeFi), NFTs, and gaming applications.
