I expect that they will run a bit longer then 60 days. Too much effort they put in website (looks much better then HashOcean) to close it so fast..
You think the website they have made is made from scratch or paid huge for that script? NO you are wrong only all these hyips use different templates rather than creating whole new website. There is no any point to support ponzi/hyip as they are only there to scam investors at last. I think yes as there first investor plan will expire after 60 days they can run away. And i am sure the first investor are themeselves so that its more than 180% return for them. They may go off saying they are hacked or their database got corrupted or some similar made up story.
Hyip are just scam and can't run long term without fresh investments.
I agree with almost everything what you wrote here, but i don't understand how they will be 180% of return from they own investment?
Do you think that they really have investments that bring 3% return per day? Or they will pay out to themselves?
