I absolutely agree with @solarwarrior
Indeed 10-20% rewards every month is not a sustainable business model and it always ends very same way.
It's a typical "hit and run" scenario and I would absolutely advise everyone to be very careful and think twice before investing.

I've tested the service: 0.021btc in about 10 days with about 0.5btc invested. Ok, this means nothing, just a testimony of experience.
Dear @oneshot
So you've invested something around 6.5k usd and you received around 250usd worth of BTC after just 10 days?
That is raising enormous red flag. That's like 4% within less than 2 weeks. I cannot think of any legit business model (except of ponzi) that would allow to benefit investors so greately.
Yours
