Ok, I've done a bundle on shares ...so I look at Gold in these troubled times. Should be soaring, right?
Who is propping up the US$? which keeps Gold lower in US$ terms. China, Russia, IMF, World Bank? All of the above?
Given their troubled economy the US$ should be in free fall!
To buy Gold now in A$ is $1300 (up about 50% in one month!!!, should've bought then eh!!) ...when the US$ tanks (IF allowed to!!)the Gold price in US$ will soar ... Our A$ will rise v the US$ .. and Gold will be in A$ ??? Up because of Gold demand or down because of AU$ rise?
Hmmmmm .. I suspect that when the plug is pulled on the US$ Gold will skyrocket in all currencies.
The dilemma is trying to buy at the right time (other than a month ago!).
