Well i will only answer what I know HP had no offices in st petersburg as btc is illegal in Russia the company is registered in Cyprus and the office was there,I tried to phone but got the same message thats on website on a recorded message.The only good thing I can bring to your attention is.

!.The coins being sold and bought on the exchanges are being bought and sold by the same people in an attempt to manipulate the price.
2.only a fraction of the premine is being sold leading me to believe HP in saying accounts were compromised and hash converted to pfc
3.It appears HP is still mining according to there pool
4.On the day of the alleged attack there IP address changed 3 times,Twice in an hour then once to put the new page up that would coincide with a DdoS attack
5. If accounts were comprised a complete audit would be necessary
6.The company was the fastest growing cloudminer in the world and I see no reason for it to be a scam.
People on forums will shout scam its gone etc but in all honesty they know nothing they just are either idiots or part of the possible hack and attack
I will make all efforts to find out as much as possible and report back here as soon as possible

I read Russian and there is no website or blog in russian that says anything fact about HP and a proven scam
