Yes there is. For thousands of years, GOLD has been, and will continue to be, the only REAL currency accepted world-wide.
But, what about bitcoin?!
;-)
Gold a valuable commodity and a beautiful one. It, by itself, will never be money again.
How would small currency be made? A dollar is about 1/1500s of an ounce. You would need a microscope to see a dollar much less a dime or penny.
Countries claiming to be on the Gold Standard with convertibility were on and off, off and on depending the needs of the nation at the time. See the history of Great Britain during the Napoleonic Wars.
Countries on the GS are handcuffed by it (see its role in the Great Depression). It would be highly impractical to impose one due to the lack of gold in the world and other reasons.
Silver would be under the same negative though less initially acute. How much silver is in a dime?
Lately, land has served as real currency. All those sky-high prices for real estate property reflects the devaluing of the dollar, which has lost much of its value since 2001. Put your money in real estate, and it gains value faster than gold.
As for interest rates, I've noticed the quickening rise of interest rates. Currently getting over 2-1/2 percent on my money, better than the measly under 1 percent not long ago. Helps me, but bad for federal debt. Debt-free and own property, that's the way for survival in the days ahead (and armed).
