IMHO this article is basically rubbish. Opinions are like you know what. Everyone has one.

Wordwide QE3 greatly argues against the perspective presented here.

There is nothing whatsoever that mandates that the USD and the gold price cannot continue up in tandem.

And as for the margin crap, it will simply serve to place gold in strong, paid-up hands and move it out of the realm of speculators/gamblers/get-rich-quick artists after a temporary sell-off, very temporary.
