I dont know how they manage to break even in 3 hours  
all i did in freebitco is turn on reward point bonus and claim free btc roll like 15-18 times daily.
and then reuse the reward point bonus all and do all over again.
i could only activate free roll bonus in like a week or two maybe ( i mean running free roll and reward point bonus at the same time)
so i am so confused as to how these users break even in 3 hours.
