Never heard of this site. But reading upon the comments of other members, it looks like this is a Ponzi so better exit early otherwise you will just lose your ether there. That's how HYIP works, you will get paid early and you think that its a legit site. So you invest your bankroll together with your profit. You are now trapped and will check your investment daily. But then when its time to withdraw them, the website will suddenly go down and just say that they are under maintenance or something. You still have hope that you can get your money, unfortunately, the site will not comeback, losing your funds all together. We all advise you to not re-invest and please heed our call.
