Not really. If they don't actually invest in mining then there is no actual profit being generated. They could be just paying from other users funds. The problem with that model is that it will collapse eventually.
As far as I know from casually reading most of the thread, he stopped investing heavily into mining hardware and worked on profits from a trading bot and other site stuff seen below.
I told that a long time ago. We are doing profit from using a users money for our BOT trading, some mining contracts (To be honest: the contracts are old, we do not rent any new hardware now!), from our ads and from our Lands game.
As far as we cannot provide an income for unlimited investments, I even will not try to discuss that it is not a ponzi. I am sure that all mines will be sold.
I am working on increasing a possibility for new investments. I think that we will add some new mines in 2016, but, I am afraid, it will not be so much new mines.
Anyway, I hope that all, who are really interested in buying will have a time to purchase mines while they are available.
+ Litecoin will be accepted soon.
