$BTC BNB (Build and Build), formerly known as Binance Coin, is the native cryptocurrency of the BNB Chain ecosystem, which includes BNB Beacon Chain and BNB Smart Chain (BSC). Initially launched in 2017 as an ERC-20 token on Ethereum, BNB later migrated to its own blockchain. It is primarily used to pay for trading fees on Binance exchange at discounted rates, but its use cases have expanded to DeFi, NFTs, and smart contracts. BNB also plays a key role in token burns, reducing total supply over time. With strong backing from Binance and a growing ecosystem, BNB is considered one of the most influential utility tokens in the crypto space.
