The site has all the warning signs of being a scam.
Promising good ROI + the fact that they have come up with a "saving" accelerator which lets them trade with less risk and more reward really sounds like a fairy-tale to me, and is something every ponzi claims to have (Some ludicrous method to justify the amount of money they are giving out/generating.)
I would personally stay a mile away from this site and it's team.
From their website:
The team brainstormed and came up with the investment automation concept for their first app, Heleum, in November 2015: a mesh network of currency values that would reduce the risk of trading while increasing the reward, compared to the inverse risk/reward inherent to the world's prevailing binary paradigm.
I always ask myself for what they would need my money if they really have found such a unique and revolutionary way to make lots and lots of money.. Surely there would be some big funders jumping up on this if it was actually real, which would ask way less ROI..
