$BNB BNB Coin, or Binance Coin, is the native cryptocurrency of the Binance ecosystem, launched in 2017 by the Binance exchange. Initially built on the Ethereum blockchain as an ERC-20 token, it later migrated to Binance's own blockchain, Binance Chain. BNB serves multiple purposes, including paying for transaction fees on Binance, participating in token sales on Binance Launchpad, and facilitating decentralized applications (dApps) on Binance Smart Chain. With a capped supply of 200 million coins, BNB employs a quarterly burn mechanism to reduce supply and increase scarcity. Its utility and integration within the Binance ecosystem have made it one of the top cryptocurrencies by market capitalization.
