From the article you linked:
KEY TO SILVER PRICE
Keep one thing in mind: the key to the silver price is monetary demand.
My question: Whose monetary demand?
For gold, it is the system. The banking/monetary system itself needs gold to recapitalize the system itself. This can be seen through the actions of the central banks.
Central banks (amongst others) are buying gold now .
Who is buying silver now? Investors and speculators, and industrial/commercial users.
I see a big problem/contradiction putting these two statements together:
1. the key for silver is Monetary Demand, and
2. Central banks are not buyers.
