It seems more than solely selling of restricted shares (illegally) in the open market. that's because SPNG was a highly traded stock. that means the majority of daily volume was shares being flipped repeatedly and not accumulation. it is a fact that the crooks behind SPNG, Metter and Moskofraud, were behind the NSS fairy tale in an attempt to cover their crimes. it is not by chance that the only penny stocks where this mythical NSS is claimed are all scams.
