It is too soon. The fact is, that NXT is in difficult position, even though It seems to be best platform right now. Yes the stigma is huge problem.
NEM will no have any stigma, so if It delivers what we think, It will in my opinion overtake NXT.
NEM has the UtopianFuture stigma. I think that is a really huge issue. Nobody wants to be a part of a project of a scammer.
