Gold

There are lot of things to measure money but gold is the prime one. Since the dawn of civilization gold is already used by the kings and rulers. Some of the artifacts are still intact to Pharaohs tomb.

A country reserve is base in gold.

I have something to confess about gold, I always buy gold every year before I go home from overseas job and to my surprise, the price of gold went high lately, almost 70% high. So I must say that gold investing is great too like investing in stock market. It never went down as far as I could remember. Collecting gold coin or ingots is an investment. There is no other time than today to invest in gold.

I don't to discuss what is gold anyway. It is an element on Earth which has bigger value than any metal out there and taken from mine.
