I believe that ETH will reclaim it's glory back once gas fee issue is solved, there is also a big difference between BSC and ETH that will still make many prefers ETH, that's the fact that BSC is Centralized and ETH isn't.
If you think ETH is not centralized you are very new to this market. BSC never roll back but ETH did in the past and that's why ETH is not as trusted anymore. Check out DAO hack and what Vitalik did in 2016. Read and learn why there are two Ethereum's, Ethereum (ETH) and Ethereum Classic (ETC). This is a serious problem in crypto-currency market. If you care about decentralization, the only true decentralized coin is Bitcoin. All other coins belong to somewhere or somebody one way or the other.
