Hello there!
I can assure you that this is not a ponzi-scheme as I myself have seen the proof for them to offering this great ROI.
Also to tell you that, this is OP's own Bitcointalk account and not another HYIP account. Which I can tell you that almost no HYIP owner who will run away with your investment does.
And for you Vasilich, you should do more research before calling a site a "scam".
Plus, no it isn't "already a scam" and it has never been.
To make sure your funds are safe they might need to do a manual withdrawal, isn't that good?
I hope that you now understand that these posts are just useless and won't do anything.
Sincerely,
Sebastian
Who are you? Are you OP friend or alt account?

Well he didn't pay his investor. Then its already SCAM..
