Yeah, I can confirm that they are somewhat sketchy. Also, with my calculator it seems like it becomes unsustainable for them between 9-12 months (depending on how many people reinvest). I was a member of gaw miners and zen miner when they first had that, and this is a little reminiscent of that. However, it does say that you can schedule a meeting, although it looks like the first available date is in August. I would like to point out that due to the amazing rewards right now, there is either a possibility of them being a ponzi scheme, or simply that they will have to increase the prices of their mining contracts (I think other companies have done this before).
Hard to guess, if it is a sustainable. The profits are insane when you calculate with reinvestments.
Your calculator shows it in an easy way.
I continue shilling my coupons. The reason is that both profit from it.
