When I first started following gold (around Thanksgiving 2007 when gold was around $800/oz), Jim Sinclair had been saying that it would hit $1650/oz by January 11, 2011 from some number of years. Leave me a comment if you know when he first made the call. He was certain of this to (and beyond) the point of arrogance.
But, he advised people to buy physical gold and to stay away from all leverage. This turned out to be good advice for the inexperienced. That's what I was. He never made any significant attempts to extract money out of his listeners with subscriptions, etc.
I think overall he has done a significant service to those who visited his site.
Thankyou, Mr. Sinclair.
