You make it sound like someone backed a truck full of Kilo bars upto the market doors and hit the dump button.
Gold and silver are leveraged at at least 100 to 1
So even I can dump 10's of thousands of paper oz without ever opening the vault :-D so the dollar goes up, Q the market to short silver and gold, push hard, trip stops, push harder, rinse and repeat,
That's my take lol...
