If you are a shill, you can fuck right off.
If by any slim chance you are not a shill and you genuinely think this site is trustworthy, you need to better educate yourself on how to detect HYIP/ponzi scams.
The site claims 2,619 users and gives out 10 Gh/s for free to each user. This means that they've given out 26,190 Gh/s or 26.19 Th/s of hashrate for free. This is roughly $2,000-3,000 worth of mining power. No real company would (or could afford to) give out this much mining power to its users for free.
They also claim an average ROI time of 3-4 months. This in itself isn't low enough to scream HYIP/ponzi, but the fact that they pay 5% referral commission (which no real company could afford), no whois data, was created less than a month ago, and allow you to withdraw without investment is highly suspect. The withdraw without investment part is designed to entice people to invest their money to make even more money. Once they see it pays out, they immediately trust it and unload their wallets into it.

Their profitability calculator indicates that I would make $0.67 per day using 1 Th/s, which is higher than what I would actually make ($0.57). Again, this alone isn't sufficient evidence that it's a ponzi, but combined with the other evidence presented here, I don't think it's very disputable.
Also, the site giving you free mining power and the site paying out means nothing about its trustworthiness. For all you know, they're doing that just to make themselves look legit so you'll give them your money.
