$BNB #bnb (Binance Coin) is the native cryptocurrency of the Binance ecosystem, launched in 2017 by Binance, one of the world's largest cryptocurrency exchanges. Initially created as an ERC-20 token on the Ethereum blockchain, BNB later migrated to Binance's proprietary blockchain, Binance Chain. BNB serves multiple purposes within the Binance ecosystem, including paying transaction fees at discounted rates, participating in token sales on Binance Launchpad, and serving as a utility token for decentralized applications (dApps) on the Binance Smart Chain (BSC). Its versatility, low transaction costs, and rapid adoption have made BNB a popular asset among traders and developers. Over time, BNB has become a key player in the crypto space, supporting Binance's mission of global blockchain adoption.
