Its saying that the investments in paper silver and silver companies could fall, because supply is running out. Physical silver tho, would skyrocket. Some people base the price of an ounce of silver, off of the stock market price, that is a mistake. If tomorrow the stock ticker says $10 an ounce for silver, all the dealers would halt sells.
Don't trust the thieves that control the stock market prices. Buy, save, and wait.
