$BNB (Binance Coin) is the native cryptocurrency of Binance, one of the world's largest crypto exchanges. Initially launched on Ethereum in 2017, BNB later migrated to Binance’s own blockchain, BNB Chain. It powers the Binance ecosystem, used for trading fee discounts, transaction fees, token sales, and more. BNB also supports smart contracts, DeFi applications, and NFTs. Its value is partly driven by Binance's regular token burns, reducing supply. While widely used and influential, BNB faces regulatory scrutiny due to Binance's global operations. Despite market fluctuations, BNB remains a top cryptocurrency by market cap, central to the Binance platform's functionality and growth.
