||BNB coin is a cryptocurrency created by the Binance exchange, one of the largest cryptocurrency exchanges in the world. Binance launched BNB coin in 2017 as a way to provide discounts to traders on the exchange. Since then, BNB coin has grown in popularity and has become a widely used cryptocurrency in the crypto ecosystem. BNB coin is built on the Ethereum blockchain using the ERC-20 standard, but Binance has since launched its own blockchain called Binance Chain, which is now used to support BNB coin transactions. The coin has various use cases within the Binance ecosystem, such as paying for trading fees, participating in token sales, and buying and selling other cryptocurrencies. Additionally, Binance has expanded the use cases of BNB coin by launching a decentralized exchange (DEX) on the Binance Chain and integrating BNB into various other applications, including their debit card and other financial services. As a result, BNB coin has become an important part of the cryptocurrency ecosystem, and its value has risen significantly over the years.
