You are very right, if BNB will remain valuable for a long time because this altcoin has grown over time, so that many crypto users are turning to the BSC network, where in addition to potentially BNB also has a very low transaction value,
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.
