As you can see another Prussian Blue Capa Derivative. If Wall Street catch  what's going on here,  some wily Financier - and I am not meaning that small confection of buttery pastry and japonaisery -  will list these on the Dow and ASX , perhaps even the Footsie, as Industrial Derivatives. And why not if one can trade Futures, ghost mortgages and currencies that drop like fermented fruit from abandoned trees? But somehow I dont think that it what our fellow here is thinking, how could there be room for such abstractions when you have a ton of metal to contend with?
