along with oil too. In fact if you pull a chart of gold, silver and oil. You will find an oddly beautiful relationship of ups and downs. Why? I only have theories. Interesting? Very!
And, to add to another discussion. When you are referring to a 70 to 1 ratio of silver to gold per/oz. Why did you use that ratio? Just curious. Historically, it has been a 15 to 1 ratio. It is currently somewhere around a 75 to 1 ratio. The big question is which metal distorted right now? Gold or Silver? ;-)
Closing thought to ponder. When Gold & Silver change in value every day. Is it the gold and silver that are changing? Or, is it the currency that is changing? Think about it! And, remember it doesn't matter where you are in the world (for the most part) silver and gold cost exactly the same throughout it.
