So I didn't know much about the Goldbacks that VK showed us the video of so I did some digging. Found a few videos of how they work when you want to spend them. The value is based on the daily value of gold in percentages. IE: 1 Goldback has 1/1000th worth of gold in it, so exchange rate is worth ~$3.98 or $4 or whatever the rate is that day. There are several videos out there so you can search for yourself. I found this one where this guy is using his Goldbacks instead of Fiat. Obviously Utah, Nevada, New Hampshire & Wyoming are now accepting them. Soon South Dakota will be too. It is explained that you can inquire to a business if they will accept them in your state if you don't live in one of these states. Anyway, I found this video, hope it helps understanding the Goldbacks which will keep or increase their value unlike the US dollar. I believe eventually all states (well most) will accept them.
