I guess the only one who can prove that this is scam is those who participated on the staking. Had they already profited or did they get what the hex team promised?
I think they can't tell that because the project is promising them the big returns after a year or more. So, they are all kind of staking and buying more for better future. It's a promising ponzi scheme to make them invest more and invite more people with their affiliate program. This is what I think at least and the truth will be revealed sooner or later !
