Binance Coin (BNB) was launched in 2017 by the Binance exchange. Initially created on Ethereum, it was later migrated to Binance’s own blockchain. BNB is used to pay for trading fees on Binance, participate in token sales, and access various financial services and applications. As Binance grew into one of the world’s largest exchanges, BNB became one of the leading cryptocurrencies, playing a central role in the Binance Smart Chain (BSC) ecosystem.
