As always this is the bitcoin world you should always be careful. I have never had a problem with this site it cost nothing to sign up, and take a look. Casimir1904, posted he took over and covered all loses made by the previous owner. I've invested and borrowed over 100 BTC, and I have a positive ROI.
With investing you have to be careful but it's very easy doable. Like I said never put all your eggs in one basket. But the site is active, and everyone does there due diligence to find scanners or defaulters.
