$BNB , or Build and Build (formerly Binance Coin), is the native cryptocurrency of the BNB Chain ecosystem, developed by Binance, the world's largest crypto exchange by trading volume.

Initially launched in 2017 as a utility token for discounted trading fees on the Binance exchange, BNB's utility has significantly expanded. It now fuels the BNB Smart Chain (BSC), a blockchain known for its fast transaction speeds and low fees, enabling decentralized applications (dApps) and smart contracts.

$BNB holders can use it for various purposes, including paying transaction fees on the BNB Chain, participating in new token sales on Binance Launchpad, and engaging in DeFi activities like staking and yield farming. Binance also conducts regular "burn" events, permanently removing BNB from circulation to reduce supply and potentially increase its value.
