$BNB BNB, originally known as Binance Coin, is the native cryptocurrency of the Binance ecosystem, one of the world's largest crypto exchanges. Initially launched on the Ethereum blockchain as an ERC-20 token in 2017, BNB later migrated to its own blockchain, the BNB Chain (formerly Binance Smart Chain and Binance Chain).

BNB serves multiple purposes within the Binance ecosystem. It can be used to pay for trading fees on the Binance exchange at a discounted rate, participate in token sales on Binance Launchpad, and power transactions on the BNB Chain. The BNB Chain itself supports a vast array of decentralized applications (dApps), including DeFi protocols, NFTs, and gaming platforms, thanks to its low transaction costs and fast processing speeds. Its utility and the expansive reach of the Binance ecosystem have made BNB a significant player in the broader cryptocurrency market.
