this is completely wrong, they're a scam.

Their team is incompetent, they've artificially increased the supply after releasing the coin, and the list goes on.

"The Hcash main chain will launch in December. Additionally, during this time the Hybrid PoW+PoS consensus mechanism will be published as an academic paper."

This already has a whitepaper because they completely copied the mechanism from the legit project, Decred.

Compare Decred's code here: https://github.com/decred/dcrd
To Hcash's here: https://github.com/HcashOrg/hcashd/

They straight up copied it and made a few extremely minor changes, mostly naming and spacing. They did make one meaningful change which substantially makes the coin worse. It was to increase the PoS reward so they can maintain complete control forever.
