$TRX What is BNB used for?

Initially, BNB was primarily used to pay discounted trading fees on Binance. However, its use has expanded to include payment of transaction fees on Binance Chain and Binance Smart Chain, participation in token sales and staking programs, and as a medium of exchange in a growing list of applications and services both within and outside the Binance ecosystem. BNB also plays a crucial role in the governance of Binance Smart Chain, allowing holders to vote on network improvement proposals.
