Excuse my amateur question but this thought hit me the other day. I have no idea in trading gold.
I always see the gold price quoted in USD. At the moment 1AUD=1USD. If you were to purchase gold now and the Aussie was to half its value to 1AUD=0.5USD, would your investment in gold double? This is of course ignoring the movement of the gold price. Lets just say the AUD crashes overnight and halves its value.
