My basic advise is don't lose money

The price of a commodity will never go to zero. When you invest in commodities futures, you're not buying a piece of paper that says you own an intangible piece of company that can go bankrupt.

Diversification is something that stock brokers came up with to protect themselves, so they wouldn't get sued for making bad investment choices for clients. Henry Ford never diversified, Bill Gates didn't diversify. The way to get rich is to put your eggs in one basket, but watch that basket very carefully. And make sure you have the right basket.

The first loss is the best loss.

Commodities tend to zig when the equity markets zag.

Not one country in existence today has had the same borders and government for as long as two hundred years. The world will continue changing.
