I cannot imagine investing in these types of assets. For those who speculate on gold & silver, would you also purchase futures contracts on oil, pigs, and grains? It's pretty much the same idea unless you are having gold bars shipped to your home.
If your objective is to make money "quickly", I'd recommend averaging any cash you have sitting around into a market-wide ETF ASAP. The trick is to not get emotional. You have to hold every last share through events just like this one. If you don't use leverage or purchase options contracts you can literally forget the stock market exists when monster events are occurring. Assuming you diversified, there's really nothing to worry about under any circumstance. Just keep buying the same market-wide funds on a regular basis. Never sell. Ever. Selling is how you lose the game.
All of this fear has created a generational buying opportunity.
