NEM technology itself has not been compromised, this is purely an exchange's fault which amounts to a drawn out decrease in price until either it is forgotten about by the general public or the price itself is deemed oversold. I do think we will return to a dollar or two on the next upcoming bitcoin rise, as the NEM foundation has been diligently working to push out updates and their progress.
Why don't you sell Nem and ride the next bitcoin wave than buy NEM after?
