$BTC BNB (Build and Build), formerly known as Binance Coin, is the native cryptocurrency of the BNB Chain ecosystem, including BNB Beacon Chain and BNB Smart Chain. Launched by Binance in 2017, BNB was initially an ERC-20 token on Ethereum but later migrated to its own blockchain. BNB is used for various purposes, including trading fee discounts on Binance, participating in token sales, paying for transaction fees, and more. It also supports smart contracts and decentralized applications (dApps). BNB has a deflationary model through regular coin burns, reducing its total supply over time. As one of the top cryptocurrencies, BNB plays a central role in the Binance ecosystem’s growth.
