This guy should be banned from ever speaking the word "Bitcoin" again. I usually don't mind skeptics but this guy is claiming that he is an expert, how can we stop this retard once and for all?
We don't need to stop him, and shouldn't try to stifle opposing opinions however misinformed or incorrect. What we need to do is expose and discredit him by continuing to publicize his failed predictions for all the world to see.
then deny him attention.
