$BNB (Build and Build) is the native cryptocurrency of the BNB Chain (formerly Binance Smart Chain) and is closely associated with Binance, one of the world’s largest cryptocurrency exchanges. Initially launched in 2017 as an ERC-20 token on Ethereum, BNB later migrated to its own blockchain. It is used to pay trading fees on Binance, participate in token sales, and power decentralized applications (dApps) on the BNB Chain. BNB also supports smart contracts and DeFi projects. The coin has a limited supply, and Binance regularly conducts token burns to reduce circulation and support its value.
