Bitcoin is still a solid leader in its place.
Regardless though we should also take into calculation the other similar coin like BNB that could eats ETH market capitalization if it has massive rally somehow moreover btc usually increase its dominance at every rally.
there is definitely chance for ETH though it's uncertain considering market capitalization always fluctuates.
How?, check on CMC, the capitalization of bitcoin is twice the capitalization of ethereum. You might think that ethereum will rise and grow and bitcoin will stand still for eth to take its place. While bitcoin is still dominating the entire market, I don't believe a single coin will perform well if bitcoin drops in price. The merge event will make a strong rally for ETH but will it last if bitcoin goes against it?
