Can you chop it into microns? One Dollar US 1 micron!
Or one grain of gold dust?
Who would even fathom of putting Gold for currency!
Easy, you buy inb multiples of the PM coin you are using. You do not buy 1 pound of feed for 30 FRN cents, you buy 100 pounds for a Silver Eagle.
Same for any other product.
Every itemI have sold on line lately is priced in Silver Eagles or Gold Eagles. You would be surprised how much of these metals are trading hands right now.
Any cellphone can get up to the minute PM values.
No you buy foriegn currency prob the yen! Or yang whatever is highest on the market and then convert to the dollar!
