I find that all alt coins are crap. They eventually all die away after they go threw their cycle.
Bitcoin is the only one that seems to stay.
Altcoin maybe crap in your eyes but you cannot deny the fact that altcoins help promotes bitcoin in every corner of the world. I can never learned of bitcoin if it was not for Dogecoins, and other member of this forum have the same experience like me. Another example of this is Pesobit that gives awareness about the existence of bitcoin to the OFW since PSB is promoted together with bitcoins.
