BNB has indeed become a very popular coin besides bitcoin and ethereum, and indeed BNB still has a lot of potential, BNB is better known to people with its binance exchange, besides that BNB also has a Binance smart chain whose gas fees are cheaper than ETH, this is why people who prefer BNB to ETH
Actually, we can see now the Ethereum gas fee is already normal since few days ago.
BNB is a good coin, but it is still a centralized coin from my opinion. Why ? because the coin can't be mined by us.
Ethereum is more decentralized because everyone can mine it with their devices such ASICS.
