$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance ecosystem, one of the world’s largest cryptocurrency exchanges. Initially launched in 2017 as an ERC-20 token on Ethereum, BNB later migrated to Binance Chain, Binance’s own blockchain. BNB serves multiple purposes: it can be used to pay for trading fees on Binance at a discount, participate in token sales on Binance Launchpad, and perform transactions on Binance Smart Chain (BSC), which supports decentralized applications (dApps) and smart contracts. BNB has gained popularity due to its utility, deflationary token model (via quarterly burns), and strong backing by the Binance platform.
