$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance ecosystem, one of the largest exchanges in the world. It was launched in 2017 initially as an ERC-20 token on the Ethereum network, but later migrated to its own chain, Binance Chain, and subsequently to Binance Smart Chain (BSC). BNB is used to pay trading fees at a discount, participate in new project launches (Launchpad), and as a means of payment in decentralized applications (dApps). It is also periodically burned by Binance to reduce its total supply, increasing its scarcity. Its versatility and utility have made it a popular cryptocurrency.
