BNB, or Binance Coin, is the native cryptocurrency of the Binance ecosystem, originally launched on the Ethereum blockchain in 2017 and later migrated to Binance’s own Binance Smart Chain (BSC). It serves multiple purposes: paying for trading fees on the Binance exchange at a discount, participating in token sales on Binance Launchpad, and powering decentralized applications (dApps) on BSC. BNB has a limited supply with regular burn events that reduce total tokens, potentially increasing scarcity. Traders use BNB for liquidity and staking, while developers leverage BSC for fast, low‑cost transactions. Its ecosystem continues expanding, making BNB a versatile asset in the crypto market worldwide
