It seems to me that reducing the fees on the Ethereum network will greatly reduce the demand for the binance network. Well, the hype around it, accordingly, will also decrease, which will soon affect the price of bnb.
We have to see that first before we can make that a fact, I'm ok with Binance chain I made 5 Ethereum trades using the Binance chain and it was fast and cheap, Binance will continue to innovate and add a lot of features, even if Ethereum fixed their fees, they are now considered as Ethereum's closest competitor and this is a healthy competition and good for the industry.
