$BNB BNB (Build and Build), originally known as Binance Coin, is the native cryptocurrency of the Binance ecosystem, one of the largest blockchain ecosystems globally. Initially launched on Ethereum, BNB transitioned to Binance Chain and later became a key utility token on Binance Smart Chain (BSC). It powers transactions, pays fees, and supports decentralized applications (dApps) and DeFi platforms within the ecosystem. BNB is deflationary, with periodic token burns to reduce supply and increase value. Beyond trading and staking, BNB enables use cases like NFT purchases, travel bookings, and financial services. It remains integral to Binance’s vision of a decentralized future.
