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.
I've been a fan of ethereum for a while but for now I'm sure BSC will be the future of crypto. Although ethereum is still the first, I feel that ethereum has been stuck for a while, especially with the problem of very expensive gas cost.
