As money currency lets say oil and dollar goes up and down. What will happen to the rest of our basic commodities? Let me think why do people invest for gold medallion or bars. Maybe It's the honor thing, sentimental value, fancy thing or its like a good collection? That you may feel your like a Nobel Laureate, Be-medalled soldier, Superstar, Special, Recognize, Superior or an Olympic Champion. I like real 24k gold to be used as medal of honor to soldiers, prize for world champions and achievers.
