$BNB BNB, which means "Build and Build", is the native cryptocurrency that powers the BNB Chain ecosystem. Originally launched in 2017 as Binance Coin, it has evolved from being a discount token on the Binance exchange platform to being the cornerstone of a vast decentralized finance (DeFi) ecosystem.

BNB was initially introduced through an Initial Coin Offering (ICO) in 2017. In its early days, it was an ERC-20 token based on the Ethereum blockchain, and its main purpose was to offer discounts on trading fees within the Binance platform.
