If they promise that money will be of no value and hound for donations, then get ready--to spend that money that will soon be thrown on the streets on silver. Do not donate anything to the washtowel. You are better off to buy silver, and if it's only small amounts, dimes and quarters are relatively easy to find and afford. You keep the silver.
That way, when the time comes and hyperinflation destroys the dollar, you will at least have something to tide you until something else comes. Instead of having nothing, you will have a few days or weeks before having to barter or find work that pays in silver or gold.
Is there anything ever posted here that doesn't somehow tie into your crazy dollar valuation obsession?
