No it's not possible because bitcoin is father of all cryptocurrency and when a new user hear about digital currency thrn bitcoin comes first. And you can see majority of the website accept bitcoin but not other coins. Abd also bitcoin is in top most position.
It is not just about being the father of all. It is being the original. Everything is just a copy. I mean really everything. Well they could say everything that this is from this or that but their are still copies.
Let us just make of use of them but dont forget to be careful.
Let us just put at this perspective, IMO, even if bitcoin is not the original but people trusted it more than the original then there is no question that it is more valuable, and a more strong assets, others altcoins also gain some trust from the investors but bitcoin is the most dominant.
