$BNB BNB (Build and Build) is the native cryptocurrency of Binance, one of the world's largest cryptocurrency exchanges. Originally launched as Binance Coin in 2017, it was primarily used to pay transaction fees on Binance at a discounted rate. Over time, BNB evolved to power the Binance ecosystem, including the Binance Smart Chain (BSC), where it is used for transaction fees, smart contracts, and decentralized applications (dApps). BNB is also used for staking, token sales, and various services like travel bookings. It has a capped supply of 200 million, with regular token burns to maintain value by reducing supply.
