This is the kind of misleading title that the media shouldn't print. This guy was actually recruiting on behalf of ISIS and bitcoin was just incidental to the story.
Sure, this headline draws more eyeballs to the article, but the editor should think twice before clearing a title like that.
That is exactly the point. The prison sentence was handed out for recruiting American citizens in to ISIS (and in my opinion, he was given a very mild punishment, should have been life without parole). Amin was in contact with senior ISIS figures in Syria, and he was trying to convince them to use Bitcoin. The leaders, however decided against using Bitcoin.
