A German entrepreneur, whose grandparents likely told him stories of the Weimar hyperinflation in his youth, has created the world's first bullion-dispensing machine. Its now fully operational in an Abu Dhabi hotel. I'm sure there are some who view this as a sell signal, as representing the final, crazed, dot.com stage of the gold bull market that began 10 years ago. I'm not one. Gold machines and coin shops are outnumbered by many multiples the "cash 4 gold" outlets that are cropping up on every street corner in major cities, which offer to buy unwanted jewelry and such. That is, as retail goes, there are far, far more buyers than there are sellers.
