BNB would probably be overcome ETH in the next few years if ETH network would never fix this issues. I heard about Eth 2.0 fee's deduction versus the current one but as many of us knows, it would be as near as Binance network fees. BNB would probably be worth more market cap than eth in the next few years for sure.
This could have happened if the effect of the launch of ETH2.0 did not really make ETH better, plus if more investors switched from ETH to BNB with the initial reason as an alternative while waiting for problems to be resolved at ETH finally felt more comfortable being in the BNB ecosystem, because that is one of the reasons for the growth of BNB today.
