This should apply to ALL commodities, with say a 10% variable to cover future production. Gold, wheat, soy beans, pork bellies etc, and all metals.
ETF's should be compelled to have 1oz of gold for every oz they have "sold" to investors.
This would stop all the manipulation and scams.
I understand there are 100oz of gold in the Gold ETF's for every 1oz of physical gold.
This is farsical and open to manipulation, as we see.
Wouldn't the 1:1 ratio show the TRUE value of commodities??
