This is not just tokenized gold.
It's a monetary system. The coins emitted will be spendable in the real world and ABX/Kinesis has already made merchant partnerships to make sure it is spendable across a wide array of PoS systems. These coins will have use beyond holding in a bear market. I will detail the differences in a future post.

The difference between fiat-backed and gold-backed is that fiat devalues constantly while gold beats inflation in the long-term. Other differences include limited supply. I will cover this as-well.
