Since the cost of Ethreum gas is expensive then many projects that use the BSC network because of the cheaper cost and very easy for us to use, but this is not a momentary development for the BSC network and this will happen even though later the cost of ethreum gas is back down, and I am very sure the two coins will continue to compete both from the price to cooperation with the bounty project.
It seems like it is very difficult to compete now because ETH has found a new ATH this month and the cost problem has also started to decline a little, and for BNB at this time the price is still below $ 1k so it is very different from ETH's price which has reached more than $ 4K for the unit price.
