Wow! That's what I call a bold statement. Are you suggesting GAZ is actually a fraudulent scheme and not just a currently overbought ETF? What about the underlying assets of this ETF, and what would be the scenario under which it would go to zero? Your prediction seems even more extreme when one considers your post script, "not kidding". I think you actually are kidding around, but I would be very interested in any support you can provide for your prognostication.
I am only expressing my personal opinions or repeating public information from SEC filings or media outlets-which may or may not be correct. Do your own investigating before investing!
