I would suggest you to strictly stick to gold and purchase in physical shape.
Dont purchase in ounces. You will lose money.
Purchase it in 1kg bar or 1/2 kg bar if you can.
1 kg bar consists 32 ounces of gold.
Gold is being traded at $1,141/ounce today. Couple of days ago it was being traded at $1,090/ounce. at $1,050/ounce (ideal price) you should get a 1 kg bar for around $34,000.
Commercial crises are just around the corner. US is printing more money then the gold reserves she has can back. The whole US Corporate bubble is about to burst. People will run to purchase saftey in gold. All that within 5 years…
Its your call. If you do decide to purchase gold then make sure
Dont get it from banks as they create a file and record. Purchase it from some desi store.
What allows me to pass opinion? Well, two year ago, I purchased (on credit line) three 1kg bars at $ 770/ounce. In other words, one of my bar is fully paid off today. 
…and I am still holding onto them because I belive the price will double very soon!
