Binance Coin, denoted by the symbol BNB, is the native cryptocurrency of the Binance ecosystem. Launched in 2017, BNB was initially an ERC-20 token on the Ethereum blockchain but later migrated to its own blockchain, Binance Smart Chain (BSC). Binance is one of the largest and most popular cryptocurrency exchanges globally, and BNB plays a crucial role in its ecosystem.

BNB can be used to pay for trading fees on the Binance exchange, with users receiving discounts for using the token. Additionally, BNB powers the Binance Smart Chain, allowing developers to build decentralized applications (DApps) and issue tokens on the platform. BNB has also become a popular cryptocurrency for investment, as its value is closely tied to the growth and success of the Binance ecosystem.
