Why a scam, NUKO team don't pretend anything to be related as a scam... It's another blockchain / clone of ETH with tokens and little hype.

stock.exhange is not very well for trade, that's sure, but was for starting, another exchange is coming fast (take a look at the discord).
Volume is tiny, because of stock.exhange or / and because nobody want to sell / buy it at this price...
Nuko need some time, but it's not a scam and creator never presented any moon target!
