Want a clue as to what non-manipulted physical markets might look like - take a look at Bitcoin.
Of course Bitcoin is in Fad phase at present - it is an off-record easily transferrable way of trading - as a store of wealth it is too volatile, but I keep a little in it. Sick of giving PayPal 3.5% of my business for what Bitcoin can do for free. I accept payment in our business now in Bitcoin, (on services, rather than goods).
For Investment - I hold ORS NST and DRM - as they have no debt, plenty of upside and do not need to go to market.
I would like to own some physical metal but am saving for another small rental property at the moment. Fixed asset with cash-flow. just sold my entire Dividend Portfolio (apart from NST) - let the bots play by themselves..
I also build soil, make container gardens and am moving towards incorporating aqua-ponics and worm farms.
