Something worries me. 1.IS Fx just gambling or does it serve some useful purpose? sorry if i offend anyone with the seemigly stupidity of this question. 2. Would it be better for the world to have one currency? Why? Why not? 3. Does a floating market (ie. price fluctuations) hurt producers in a country...? or hurts anyone?? or is it better for evryone that the floating market stays as opposed to introducing one world currency, or fixed currencvy rates ...??
