[in bitcoin it all started so it is impossible to be surpassed by other altcoins as long as bitcoin continues to exist it will not disappear but it is also possible because there are other alt coins popular and used by people
Which one? Bitcoin is not gonna disappear anytime soon because as long as internet exists, Bitcoin is still gonna exist even altcoins are getting the popularity over Bitcoin.
I don't know why people being so skeptical because altcoins are getting used by more people, yet Bitcoin is still at the top :d
