I doubt hashocean run real mining, without proof of hashing it's just a fake mining.
who cares if its real or fake mining... until we are getting paid.. we wont mind
its very important, they are real mining or not, because if they are real mining and are legit, there is big chance that we will get ROI and profit, but if they arenot mining and are ponzi, there is big chance that we will be scammed before we will get ROI
