As i understand, at this time Dev has noplans to put that coin to the exchanges, they got something behind the coin that takes most the time. so i'll mine it for future.
The dev said he will list NNC on Cryptopia in September.
Take great caution though as he scammed people out of their NNC in exchange for worthless NNT that is on the Waves platform, in order to get his hands on as many NNC as possible. He refuses to verify NNT on waves because that would expose his identity to be caught for the scam he is pulling. At least the people that stil have NNC (the few that he does not own after his swap scam) will be able to dump on Cryptopia soon. Then there is the self moderated topic that will be next so that warning messages can be deleted by the dev.
