So I invested into this and in the end asked for a refund as they have a full refund policy.
"We guarantee you the full refund if you don’t like our service operation for any reasons. You need to inform our service desk about your desire to have your invested funds back. You will get them on your balance in 72 hours and in 24 hours funds will be transferred on Bitcoin-wallet that was provided in settings."

If you do the math this ads upto 1.13216 btc. What I got as a refund was 0.76014561 btc. They sent an email for each transaction number for each of my purchases but gave no refund amount specific to each refund.
"You have received refund upon the following request:
Order #674969
Upon request, these powers are switched off.
Happy Mining!
Team HashOcean"
Granted these guys may not be a ponzi site specifically but be warned that their so called refund policy is adjusted to what ever they feel is the most beneficial currency for them not what you invest with. Far as i am concerned it is just another site to get burned at.
