Hmm, some anon on the internet warning that posing as an anon is a suspicious sign. Thanks for the disclaimer.
In this way, you want to justify the lack of answers to good questions?
Well, maybe they´re not interested in advertising their identity to
extortionists and other anon criminal garbage.
I´m not justifying anything. Just considering more than one possibility. What one-track minds and other anon morons do is their concern.
Anyway we will not see any answers so it isn't worth of our time..

Rather than fighting here take a small piece of advice from my end. Get a new contract @ their new rates. These are paying exceptionally well. I got this notion from a discussion at their forum and it has worked. This is how your old investments will get covered. Decision is yours. Over to you...
So i have to buy new contract to cover my loss from old one?? If this what are you talking is true - you are talking straight about ponzi..

I dont wanna pick up another fight regarding Ponzi or Not. IMO, if it were a Ponzi, it would have blown by now because of the low rate they are selling from beginning. In fact, most of the Ponzis are now blown. All the current players are doing fractional reserve mining. That is not my concern though. What I have learnt from their forum, that they used to map different contracts to different mining blocks before. Hence, we used to see, different mining results by different miners. Now, as BTC price has plummeted, support cost of people having bad luck has increased so much that they are complaining. If you notice closely, everyone is not complaining as some are definitely getting good payment. But, as it seems to me, the new contracts after the price rise, is same average for all. At least, that is what appears to me and it has nothing to do with a Ponzi. That is why, I'm suggesting that you might try that out. Though, if you think it is a Ponzi, you should not...
