Mere semantics, squire. Mere semantics. Definitions that differ. You can find one I can find others. All inconsequential.
I am still waiting for your explanation as to why gold has such a low DMU if it is a mere commodity and why it is kept as an asset by central banks. Russia and China are currently increasing their gold stocks in favour of US$ treasuries.
Please also define for me a US$. Please don't say the United States unit of currency as this is what it is used for and as such would be a circular argument.
