A friend of mine lives in Frankfurt and checked out the building for me. No indication of a company named Xtreme Miners or Jorge Berg whatsoever.
Well I actually visited the adress of vmc (virtual mining corp), and there were no signs of the company there as well. But they actually deliver.
So I think just because they dont have the name on the doorbell plate, doesnt mean the office isnt there I suppose they do this so that no customers/ journalists ring all the time
Anyway you guys are really speculating a lot here, either get it or dont .. I would have got one if I hadnt ordered from cointerra already
