So far, so good. I have a 3 BTC commitment with these folks (12 of the 250 GH/S accounts) that I started mid April 2015. So far, I've gotten daily payouts and the numbers check out. There's a few suspicious things, like not knowing where there data center is and not seeing a lot of other info on the site, but as of 6 weeks in, it's been doing as promised. I'm fearful to make a bigger commitment, but thus far I'm about 30% of profitable, so if this keeps up, it should be profitable from my invetstment in about 2-3 months. If anyone else has any experience, I'd like to see it.
