I have seen absolutely nothing to suspect that this coin is a scam.  And I would know, I bought QuarkCoins whilst Bill Still was pumping.  So my scam-radar is pretty finely tuned now.

The coin has some fantastic tech behind it (OBFS4, stealth staking coming shortly, staking donation slider, lots more).  It has easily the best community of any crypto I've been involved with, and there is no shill team involved anywhere.  Come join the slack channel if you think otherwise.
