$BNB BNB (Binance Coin) is the cryptocurrency of the crypto exchange Binance. It was originally created in 2017 on Ethereum, but later migrated to its own blockchain "BNB Chain". BNB is used for many purposes: to pay trading fees on Binance (with a discount), as a means of payment with partners, or for staking. Additionally, BNB is part of many decentralized applications (dApps) and smart contracts. The supply is limited: through regular "burns," BNB tokens are destroyed to reduce the quantity and stabilize the value. BNB is one of the largest cryptocurrencies in the world and plays a central role in the Binance ecosystem. It is therefore more than just a coin – it is a versatile tool.
