$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance exchange, originally created as an ERC-20 token before migrating to its own blockchain, Binance Chain, in 2019. Initially designed to pay for trading fees on the Binance platform, BNB has evolved into a versatile token with numerous use cases. It powers decentralized finance (DeFi) applications, acts as gas for transactions on the Binance Smart Chain (BSC), and is used in staking and governance. Binance periodically burns a portion of BNB tokens to reduce supply, aiming to increase scarcity and value over time. BNB plays a central role in the broader Binance ecosystem.
