Ok, So I invested .1 BTC last month and raised a refund for it and got it back successfully. I am going to invest .5 BTC*2 out of which I will enter into system with .5 and will raise a refund for another .5 BTC. Assuming they only return small amount lets see what happen with .5 BTC.
Another thing is that I have met few people on the web and spoke on the phone who are getting payouts since almost 15 months now and everything is fine and regular for them and they don't have any chain or anything under them. One of the person invested only 1 BTC and another invested around 3-4 BTC's and things are good for them.
I have takes the risk of a small amount, lets see what happens next. At least I will understand how it actually works and even if I calculate things more incoming and less outgoing basis I guess this thing is gonna run long long way.
Will share more details soon.
