I am 99% sure they are just ponzy scam scheme and waiting for enough naive investors to take they coins and run.
The payout details that they posted proves 100% that they are running a ponzi. That's a guaranteed fact that with irrefutable evidence. They are taking the money paid to them, sending that money to their payout address and then paying a fraction of that money back to the customer's address from which it was originally sent.
Ask them if they have a response to the scam accusation and let us know how they respond.
