Besides, billionaires don't always make the right decisions.
Let's talk about the time that Warren Buffet bought about 129 million oz of silver at $3.50 to $4/oz. around 2002-2003. Then he dumped all the silver in 2005 around $6/oz. Good timing on a great trade, right?
By 2007 silver was up to $17/oz.
By 2011 silver was up to $48/oz.

Yeah, what a loser, only made 260 million buckos. And it took a whole two! years! That is, like, a LONG time.
