I don't think someone can actually say it is legit or not because not only but so many people have profited and benefited on bitcoin in so many ways that you can imagine. I mean not all people might like this currency but bitcoin isn't built for everyone. The target of bitcoin's purpose lies in the anonymity of it's user so don't lump us bitcoiners to all of you so please don't raise substantial matter if it's legit or not bitcoin doesn't care nor you haters.
