BNB is one of the most popular cryptocurrencies in the world, powering the Binance ecosystem. Originally launched as an ERC-20 token, BNB later migrated to its own blockchain — Binance Chain and Binance Smart Chain, now merged as BNB Chain. It is used for paying transaction fees, participating in token sales, and accessing various DeFi services. BNB’s limited supply and strong utility have made it a favorite among traders and long-term holders. Whether for staking, trading, or paying fees at a discount, BNB remains a key player in the crypto space with growing real-world adoption.
