So gold pays interest?? Did you really believe what you posted AuAg or just see it as another misinformed post to promote gold as a good investment. Even a cursory look at the logic reveals holes wider enough to drive a mining truck through. Use the same criteria and using the historic POG from Kitco dating back to 1980 reveals that had you used this investment logic, by 2000 you would have been bankrupt (both financially and ethically) as an investment advisor. So your $100,000 1980 dollars would not have been available to invest and earn "interest" on in 2000.
The author of the original article Peter Souleles B. Com. LLB. must know this and, that he writes such an article ridicules the whole industry. If you want to promote gold, you can do better than promoting misinformation. Gold is a good investment at this point in economic cycle. Anyone who got in at the right time has set themselves up.
