Re: FreeBitco.in - Contest with $30,000 in GUARANTEED PRIZES now live!
I have argumented these numbers for years, but the standard answer is always " Not every user of Freebitco.in is registered on this forum " , so we are not going to get more than that. 
Not only are most of our users not on this forum the vast majority of them prefer to enjoy their winnings in private. Why do you find a forum post of a screenshot of an email more convincing than a provably fair system?
