Binance Coin (BNB) is a cryptocurrency created by Binance, one of the world's largest crypto exchanges. It was initially launched as an ERC-20 token on Ethereum but later migrated to Binance Chain. BNB is primarily used to pay for trading fees on the Binance platform at a discounted rate. It also plays a key role in the Binance ecosystem, including Binance Smart Chain (BSC), a blockchain for decentralized applications. BNB can be used for payments, token sales, and even travel bookings. Its value is influenced by Binance’s performance, quarterly token burns, and overall crypto market trends. BNB remains a top altcoin.
