Yes, the "Peter K" guy seems not to be a normal investor. I noticed that also. you are certainly right.

Concerning marketing side, i was just saying that at the beginning they really planned to use the mine to install the farm....They understood afterwards that it wasn't a good idea.

They can't exit scam like that : they gave their names, the owner has one apple shop in Almaty, there is probably a registered company in KZK (should be interesting to get the company registration by the way...i think it's public information), they raised a huge amount... and there are laws!
I still think that they don't plan to scam...it's just that they launched the project with a lack of experience.
Someone just "ragequit" i think and so "decreased" the price till 0.00096 ETH/ROCK2...I really think that it will not remain at this price for a while...we are all just disappointed that they don't reach full capacity faster! (disclaimer : i'm rock2 token holder)
And anyway, keep in mind that if competition for mining is hard in 2018...When you get electricity cheaper than competitors in a quite cold country, you have a huge advantage.
