But even with cloud mining, profit they promise is way too high and I don't see how can that be sustainable, without them constantly loosing money. Renting 1000 MH/s for 3 years is very expensive, and yet they will charge those that buy the phone only fraction of the real price.
Let's say they've just done a publicity stunt and yeah, the phone comes with a mining contract...
Even if they would try to build a mining company with money from phones, it would be impossible.
The best, absolute best gear that's on the market that could deliver 2 eth a month means one and a half Inno A10 for each contract, but the starting price for that gear would be 4500$, 4.5x times what they get on for the phone, and 2x times what they get fro the plan, and it would also imply they take the hit for the electricity. And!!!!...it goes with the assumption that Buttercup doesn't wake up in one morning in a bad mood and we see ETH going POS.
Nope, cloud mining, or phone mining, the revenue is in any way impossible for that amount.
I doubt it will even manage to become a ponzi, as I think it is close to impossible for them to pay even a few clients for more than a month.
At least the Finney phone was legit, this one is pure garbage.
