As the dollar goes to 80, and interest rates start up, and fear rises, and as 10yr yeilds go up cause bonds crash, and deflation deflates, and gold gets closer to a standard again, gold prices will get closer to its shadow price based on money supply as gold supply runs out.
As gold does this, and ends between $5k and $15k within 20 years, you will see companies like Banro go from pennies to tens of dollars per share.
