Their site is down right now.... It definitely is a scam... BTCs gone, these guys are gone for good... they ran away with some 14,000 BTCs, some of them mine 
...!
...!It s not down but it does not make a difference for people who lost money on this one. The funny thing is that people who lost money on this one are generally also involved into cloudminr.io, which ll go down next. They say this is a risk differentiation, between Ponzi and Ponzi.
That why price of bitcoin very hard to up, so many scamer get BTC from ponzi, This is like bitcoindouble in the last year,
