All I can say about Hashocean is that on October 2nd 2015, I cautiously opened 10 accounts to take advantage of their free 15 KHS bonus, I purchased 20 KHS for 0.02650 BTC on each of the 10 accounts, I made ROI on January 7th, 2016 and have mined a total of 0.06834067 BTC on each of the 10 accounts (current net profit is 0.06834067 BTC - 0.02650 BTC = 0.04184067BTC)
Notice that I only played small amounts and it was only to see how it plays out. For these small amounts, the investment worked great and the same on all 10 accounts, but there is no guarantee that the same would happen for larger amounts.If its a ponzi, when large amounts are invested, the website may shut down and steal the money...
They are still giving the 15 KHS free and forever for new users also when I opened the 10 accounts, I used my initial account referral link and got an extra 1 KHS from each of my secondary accounts:
https://hashocean.com/?rid=215632so in summary, for my 10 accounts, I invested a total of 0.265 BTC (about $60) on October 2nd, 2015
I broke even on January 7th, 2016 on the 9 secondary accounts
I broke even on December 27th, 2015 on the primary account (with 42 KHS)
Mined a total of 0.0820377 until today on the primary account. A profit of 0.0820377 - 0.0265 = 0.0555377 BTC
Total cost = 0.265 BTC
Total revenue = 0.615 BTC (from 0 secondary accounts) + 0.0820377 BTC (from primary account) = 0.69710373 BTC
Total Profit = 0.69710373 - 0.265 = 0.43210373 BTC
I am not trying to promote Hashocean or anything. I am just reporting the results of my little hashocean experiment. Although it seems legit, you never know if they suddenly decide to stop paying and take our money away... As always, with things that are not 100% guaranteed to be legit, invest only what you can afford to lose!
