^ That.
I'm also pretty new as far as investing, but I'm incredibly wary of putting my money in anything that promises payment in a failing,* unbacked currency. It's like giving the government an interest-free loan. I recently converted a bunch of bonds I've been sitting on into other assets when I calculated how much purchasing power had been lost due to inflation. And the government says these bonds account for inflation... my ass!
*While the dollar hasn't outright crashed, do keep in mind that it has lost 98% of its purchasing power since the creation of the Federal Reserve. One should look into things that will at least keep up with inflation or hold their value when the dollar inevitably croaks. To get an idea of the real inflation rate, just look at how prices increase on the things you buy regularly.
