There are some who say theat silver has huge upside because there is a supply deficit, unlike for gold.
There are huge stockpiles of gold around the world, such as in the vaults of central banks.
Gold may be used for jewelry or coinage, but it is rarely lost or destroyed.
Silver, on the other hand, gets used in industrial applications and is lost.
There are smaller stockpiles of silver, and these are being depleted.
In addition, most silver is produced as a byproduct of Copper, Lead, Zinc mining (all of which are rapidly being cut back!)
