$BNB BNB is the native cryptocurrency of Binance, one of the world’s largest cryptocurrency exchanges. Originally launched in 2017 as an ERC-20 token on the Ethereum blockchain, BNB later migrated to Binance’s own blockchain called BNB Chain (formerly Binance Smart Chain). It serves multiple purposes within the Binance ecosystem—users can pay trading fees at a discount, participate in token sales, and access various DeFi and NFT platforms.

One of BNB’s key features is its quarterly burn mechanism, where Binance buys back and permanently removes a portion of BNB from circulation to reduce supply and increase value. This deflationary model has contributed to BNB's price growth over time.

Beyond the exchange, BNB fuels a growing ecosystem of decentralized apps (dApps), smart contracts, and blockchain games. With its fast transaction speeds and low fees, BNB Chain has become a strong competitor to Ethereum. As Web3 evolves, $BNB remains a central player in the crypto economy.
