NB (Binance Coin) is the native cryptocurrency of the Binance ecosystem, one of the largest cryptocurrency exchanges globally. Initially launched in 2017 as an ERC-20 token on the Ethereum blockchain, BNB later migrated to Binance's own blockchain, Binance Chain.

BNB's primary use case is to facilitate transactions on the Binance platform, offering users discounted trading fees when used. However, its utility has expanded, allowing users to participate in token sales, pay for goods and services, and more. Binance regularly burns a portion of BNB supply to increase scarcity, which can drive its value.

As one of the top cryptocurrencies by market capitalization, BNB plays a significant role in the broader crypto economy, making it a staple for Binance users.$BNB
