$BNB is the digital currency of the Binance platform, used to pay trading fees on the platform with special discounts, and can also be used in many digital applications and services. It started as a currency on the Ethereum network, but now operates on its own #BNB Smart Chain, making it faster and cheaper in transactions. $BNB continues to expand with strong support from Binance and is considered one of the largest digital currencies by market value. A portion of the profits is used to periodically burn BNB, which reduces the supply and increases its value in the long term.
