Even if this is the case, and is all above board, I would hazard a guess that it would go south soon enough. Good shit always does.
As the OP already mentioned on his title thread, it is new. So high likely that the site is giving good returns for now, to attract users. But later on, just like any other crypto earnings site, they won't give back anymore. So for the OP, be very careful sending more money into this site. Much better if you can recover your initial ROI and the profits will only be left on the site for further earnings. This can easily turn to scam and the owners will disappear without a trace.
