In the past year alone Gold in Australia has gone up nearly $2000 for one little one ounce coin. It has gone up more here because our currency (Paper Money) is valued differently. It is more expensive in a sense, but so are our burgers.
Let me Explain. In America a Big Mac can cost between $7, in Massachusetts, to $4 in North Carolina and Wyoming ( I have removed the decimal points and cents to make the Math easier ok). Now the difference in price is because wages in Massachusetts are high, Massachusetts has some of the highest average hourly earnings in the country and people can afford to pay more for a burger. In Australia though our wages are a lot higher again, and we pay $11 for a Big Mac. Eleven Dollars, one more dollar than a ten dollar bill ok.
With that out of the way let's look at Gold again.
Because the price has gone up $2000 an Ounce here (for one small coin) I can now buy 182 more Big Macs than I could a year ago. So I could sell the coin for cash, buy 182 Big Macs, and still have the money I started with a Year ago.

I'll leave it as an exercise for you to work out how many Big Macs you could buy in Massachusetts with your Gold price of $3685 and a yearly profit of about $1200. Don't worry if you can't, that's pretty advance math for Americans hey

Just remember, with Gold you can buy a lot more Big Macs in the future, that's the key.
We're 17 years past the peak now and the 3rd World is going hungry and dark. We'll be next, we're well on the way in fact.
