#BNB (Binance Coin)* is the native cryptocurrency of the Binance ecosystem, originally launched in 2017 as an ERC-20 token on Ethereum before migrating to its own blockchain, *BNB Chain*. BNB was created to offer users discounts on trading fees within the Binance exchange, but its use has expanded significantly. It is now used for transaction fees on BNB Chain, token sales, DeFi applications, NFTs, and even travel bookings and payments. BNB has a limited supply, and Binance regularly conducts token burns to reduce circulation, increasing scarcity. As Binance grows, BNB remains a core asset in the global crypto ecosystem.
