Even then I have not heard form anyone here if they had won a lottery. Few of my friends also play at freebitco and they also did not win any big prize. I wonder if this lottery system is fair ?

Recap how many people you know who have won in the standard lottery of your state? I am quite sure it's "none", would you call the States lottery unfair, too? Regarding the freebitco.in lottery: There are millions of players all over the world, chances that you know someone who has won in the lottery personally are extremly low, just do the math.
