BNB, or Build and Build, is the native cryptocurrency of the BNB Chain ecosystem, initially launched as Binance Coin in 2017 to offer discounted trading fees on the Binance exchange. Its utility has since expanded significantly. BNB powers transactions on the BNB Smart Chain (BSC), enabling decentralized applications (dApps), DeFi activities like staking and yield farming, and governance participation.
The token also sees real-world use for payments, travel bookings, and online services. Binance employs a regular "burning" mechanism, reducing BNB's total supply to maintain scarcity. With ongoing ecosystem upgrades and increasing adoption, BNB remains a prominent asset in the crypto market.
