$BTC BNB (Binance Coin)** is the native cryptocurrency of the Binance ecosystem, launched in 2017. Initially designed to offer discounted trading fees on the Binance exchange, BNB has evolved into a versatile digital asset. It powers transactions across Binance platforms, including trading, fee payments, and participation in token sales. BNB also fuels the BNB Smart Chain, a blockchain that supports decentralized applications (dApps) and DeFi projects. With periodic 'burns' of tokens to reduce supply and increase scarcity, BNB combines utility with deflationary mechanics. Its broad use cases—from travel bookings to financial services—have solidified its position among the top cryptocurrencies by market capitalization, reflecting Binance's growing global influence.
