Probably doesn't know better.
He may not understand the definition of a ponzi, but at least has admitted to the fact that all cloud mining companies do fractional reserve mining(which is a form of a ponzi operation) and that he doesn't care about this dishonesty like a typical sociopath. This is why he/she is disgusting.
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...
This is why you have to buy cloud miners that had to be bought as physical miners in the first place, only pay for the provable blocks and send the no longer profitable miner to you, if everyone did this it would be a lot better cloud mining world.
