Well, it's no different than many scamming pennies out there. This one seemed to have good promise but as it turned out, just another scam. GRSO management, I challenge you to prove me wrong!!! =)
If this is like many others, my guess is that it may drop to much lower level, say 1 cent, than company pumps some news to prop sp to say 3 cents and bunch of people will tell you sky is the limit. New investors/bag holders come in and allow company to dump more shares. Than its the end of good time. Price will be sub-penny.. just my guess or until the company proves me wrong.
