BNB is the token at the center of Binance, the world's largest crypto exchange, and also the native coin of BNB Chain (Binance's fast, low-cost smart-contract network). That dual role is the key to it: BNB gives trading-fee discounts and perks on the Binance exchange, and it's the 'gas' you pay to use BNB Chain's DeFi apps, stablecoins and games. Binance regularly 'burns' (permanently destroys) BNB to shrink the supply toward a target of 100 million coins, which is meant to make each remaining coin scarcer over time. It's one of the largest cryptocurrencies by market value.
Where it stands today: BNB Chain has become one of the busiest blockchains by daily active users, with billions of dollars in stablecoins and DeFi value, and it's now pushing into AI-agent infrastructure. The burn mechanism keeps steadily reducing supply. But BNB's fate is tied tightly to Binance the company, which remains under regulatory scrutiny in the US and elsewhere over compliance and money-laundering concerns; leadership changes have come alongside a stronger compliance push. So today it's a high-utility, deflationary token backed by a dominant exchange — but one whose biggest strength and biggest risk are the same thing: Binance itself.
