Of course we are still using euros & dollars, because up to now, no other currency could overcome the bootstrapping problem of network effects, to be useful. Bitcoin is changing that. Thats why we are all here, on the bitcoin forum.
I am here to tell you that you are an idiot. I'm in the educational sector. It is my calling.
