$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance ecosystem. Originally launched in 2017 as an ERC-20 token on the Ethereum blockchain, BNB migrated to its own blockchain, Binance Chain. It is used to pay fees on the Binance exchange, obtaining discounts on rates. Additionally, it serves as a base for transactions on Binance Smart Chain (BSC), a network focused on smart contracts. BNB has a limited supply, which enhances its value. Binance conducts periodic "burns" of tokens to reduce supply, increasing scarcity. Its adoption has expanded, being key in DeFi, payments, and decentralized applications.
