Sorry to all people who got screwed but this is what happens when you deal with something that is not regulated.
Why it must be regulated? Not everybody wants to be a slave of the USA. Why should bitcoin be regulated? Tell me, why should it be? Yes, of course, the fiat billionaire motherfuckers will take this last thing of freedom away, as we can see with btce, but no, in no way it must be regulated from the view of the people.
