Thanks for the explanation, JBMat. What about investing the existing cash savings into, lets say, fine firearms right away?
I'd say investing in any useful firearm or ammunition is a good investment. Pick a useful firearm or ammunition. Track prices over the last 7 years. I found their values (measured by the market prices) increased more than ANY other investment I have. It's not even remotely close.
Note that cash (e.g., U.S. Dollar, Japanese Yen, etc.) can decrease in value just like any other investment. Cash is desirable because it's convenient. That's a big advantage, but I see no unique benefit otherwise.
By the way, I just compared the Japanese Yen to the U.S. Dollar. I wish I had been exchanging my Dollars for Yen over the last several years!
