Every little bit helps. BNB (Binance Coin) is the official cryptocurrency of the Binance exchange and the BNB Chain ecosystem. Initially launched in 2017 as an ERC-20 token, BNB later transitioned to its own BNB Chain. BNB has many practical uses such as reducing trading fees on Binance, paying for goods and services, and participating in decentralized applications (dApps) and DeFi on the BNB Chain. BNB also plays an important role in network governance and the periodic token burn mechanism helps reduce the total supply, which can affect value. With an expanding ecosystem and diverse applications, BNB is one of the largest market-cap cryptocurrencies and has significant influence in the crypto space.
