Well there is the possibility that it may not be legit but i think it is too soon for it to go off line if it indeed intend to. Their business model allows them to keep going for a long time but still I do not see how they can be sustainable in the long term.

It better be :)

Just dont use it xD

Too late for us now :D

They posted a tweet saying it's down due to server maintenance.

I hope for all the users it's going to be up soon... But my gut feeling tells me this is a Ponzi. I just don't get how those kind of profits could be sustainable...

I have a feeling you are right sir. Everything is a ponzi.
