Peter Degraaf , sehr erfahrener Trader, ist davon überzeugt. 
Und zwar in einem sehr lesenswerten Artikel über den weiteren Gold - und Silberanstieg:
"....COMPARING GOLD TO SILVER
The bullish case for gold, that has been made in this article, is even more powerful for silver. Whereas most of the gold that is used, eventually gets recycled, most of the silver that is used, ends up in landfill. Small amounts are used in every cell phone, computer, refrigerator, TV set, laptop, satellite, electrical switches, medical wound coverings, water filters etc.
The 2.5 billion ounces that existed in US government stockpiles when I first became interested in silver in the early 1960's are gone! Used up! Finished!
During the recent drop in silver a few weeks ago, the number of ounces in the SLV, silver ETF actually increased! A very bullish development!
Silver seems to bottom towards the end of each quarter: March, June, September and December often carve out a bottom in silver. The drop in March came right on schedule.
THE RATIO BETWEEN GOLD AND SILVER
It was my pleasure to meet Mr. Nelson Bunker Hunt at a convention; just after the Comex board changed the rules on silver contracts, and finished his run at silver in early 1980. I asked him about the gold to silver ratio. He told me that he felt that in time, the ratio would shrink to 10 ounces of silver for an ounce of gold. More than 25 years have passed since that conversation, and many more uses for silver have been discovered. Less and less silver is being found. Due to environmental concerns it is more difficult now to open a mine than at any time in history. (Congress is currently discussing mining legislation HR 2262). It is my belief that the ratio between gold and silver will shrink in time, to 5 ounces of silver buying an ounce of gold....."
