Does anyone have any idea that how much approximately they have raised from users for mining ?
Nope. And I'd say that the BTC are lost - unless someone comes forward with some useful information. Until now, the only information we have is that there is no information.
Probably we should set up a reward system for future cases like this...
A couple pages back there was a guy trying to get a list going of amount lost (just on cloud hashing purchases). I'd advise all to start adding to the list so we can get the Swedish police on the case. It was absolutely fraud. It's also annoying how they tried to delay us investigating them by coming up with excuses.
