Bitcoin dominance in the crypto market almost 51% right now. If bitcoin price will go to the moon again then this dominance percentage may increase! But we have many options in altcoins, and many altcoins are better than bitcoin in several ways! Do you think, in future, Altcoins will dominate the crypto market? Or will it be a strong competitor to bitcoin?
I think that would be really hard for any altcoin to surpass the Bitcoin for now, as long as the image of bitcoin as the mother of another altcoin still sticking in the mind of people, that will be impossible for altcoin to surpass bitcoin domination.
