Let’s talk about BNB Chain:
BNB was first issued in 2017 as an ERC-20 token on Ethereum, then moved to the Binance Chain mainnet in 2019.
On BNB Chain, BNB is used to pay transaction fees and for validator staking, among other things. Its use cases are directly tied to on-chain activity.
$BNB 744.77(+0.5%)

Just my personal take—it may not be entirely accurate, so please think critically.
