Depends what your goals are. Let's say there are three general goals:
*Total economic collapse
*Hedge against currency debasement
*Speculation
Total economic collapse, I don't see it being very divisible and useful for emergency commerce between producers. Frankly, if the lights go out, there won't be producers to trade with. If the trucks stop and there's no power, nobody is going to have much to trade. You're better off, not with food, fuel, defense, and medicine, but rather the ability to produce food, fuel, separation from danger, and avoiding the need for medicine. Probably not a bad idea to have some, but I wouldn't bet the farm on just bars and coins as a means of survival if we go the way of every other fiat money system in the history of the world run by crooked devil worshiping pedophile bankers.
Hedge? Totally different. I also like Sprott funds. I think at the pace money is being printed now to keep Israel bombing 6+ countries at once will quickly drive the dollar into the ground. I've felt for a while now that precious metals do not match pace with the destruction of the dollar, but they do keep pace with the cost of production. It seems mining is always on the brink of collapse no matter what the gold price is. If they can make money, they blast and leach. If they can't, they stop until the price comes back up.
Speculation? Good luck. There is no honor or law in the commodity markets.
I'm about 7% in vaulted precious metals with Sprott. I don't envision going much deeper from here. It's more a compliment to ultra short term treasuries right now, which I consider both alternatives to cash.
