Because you still keep using bitcoin and its snet effect it is spread around the people in the world
you don't need to accept a bunch of altcoins,just accept bitcoin
Pretty much this. Altcoins are just a hindrance, people are creating them as pump and dump in order to earn quick money almost in 100% cases.
Most of them are copy paste or existing code without any changes beside name of the coin. Instead on focusing our attention on altcoins why don't we focus and upgrade bitcoin?
It would beneficial for us a lot more than creating new altcoin everyday. I think going pro sidechains are also not the way to evolve... Only pure bitcoin is the way. Stop deviations.
