Mary Anne and Pamela Aden are among the advisory world's top authorities on metals and resources.

In a recent Q&A session, the editors of The Aden Forecast answer the most common questions that they are asked by readers as to the current state and future outlook for the precious metals markets.

In addition, the sisters answer what they say is the most frequent question they receive: "What is the best way to buy gold." Here, they offer a review of five strategies for investing in gold, including their top picks among stocks, closed-end funds and ETFs.

"There's no question these are dangerous times and the financial world is in uncharted waters," caution resource experts Mary Anne and Pamela Aden.

In The Aden Forecast, the sisters offer an exceptional in-depth discussion on inflationary vs. deflationary foreces, their outlook for precious metals, and their top gold and silver positions for long-term investors.

"The global financial system is on very thin ice, teetering on collapse. Global central banks clearly are literally pulling out all the stops to revive lending and the world economy.

"Will these efforts work? Will they be enough? Those are the most important unanswered questions of the day and only time will tell, but we should know much more in the critical month or so ahead. Why?

"The Fed is spending money at an astronomical rate. It's creating this money out of thin air by monetizing bad debts and whatever else it has to. Remember, this is on top of all the other ongoing government expenses and it's extremely inflationary.

"Normally, there is a lag of about a year or so between money creation and inflation but eventually, what's recently happened will result in massive inflation, a much lower U.S. dollar and a soaring gold price.

"The bottom line is this, if the banks start to lend again, then the economy will be on the road to recovery and inflation. But we know the banks are scared and they're being extremely cautious, for good reason.
