I don't think that it's a ponzi scheme. I believe they have the actual hardware and are actually mining coins. A ponzi scheme would suggest that they are simply taking new investment money and paying old customers with it. I'm almost positive that is not true based on what I've been reading, and in actual dealings with them. I think they are just literally running a large virtual operation where they don't attach specific hardware to specific people. I think they have a large pool of hashrate and are paying people based on hashrates paid for, not physical hardware that people own. It doesn't seem like a bad idea really, but we'll see. I've been drilling their forums with questions, trying to figure out more information. I do trust their company and have received products from them in the past and have had no issues with them at all. I don't really trust their prices or their ability to generate profit for customers which is why I keep asking and asking.
