you know in some countries they try and track all your activities and mining earnings to make you pay taxes or shut you down completely
I guess some just avoid providing such proofs, it doesn't necessarily mean they are ponzi or scam. only is scam if you provide some proof
Example is some one making a thread and posting with evidence that they got scammed by some cloud mining service.
If there is any such thread and accusations regarding hash ocean please let us know, because I would like to know such a thing fast to avoid
Investing any more money and time in their service but otherwise you all can say whatever suits you best, so far I got ROIed with them
And continue to do so, only though with small amounts
