there's more innovation in altcoins than in bitcoin
no so hard to see that
NFTs and all the Defi current structure came from altcoins, not bitcoin
but innovation per se isn't the same thing as driving prices up
bitcoin ngu technology works well because it's simple
It is not the technology and innovation that makes a cryptocurrency scarce. It is the demand that makes it scarce. Even if there is a cryptocurrency that is highly advanced if there is no demand for it, it is only highly advanced but not scarce since no one is taking interest in it.
I think the factor that differentiates scarcity from other things is the number of people who demand it. Those who are willing to pay no matter how much they have to pay for it makes up for what scarcity is. In short, the vast number of demands overweigh the supply of the cryptocurrency which is why Bitcoin can be considered the most scarce cryptocurrency existing today.
