Take note that in freebitco and every other casino, there's a house edge which guarantees that you will lose in the long run and it may worth mentioning that the house edge in freebitco is 5% which is higher than any other casino I know.
Remarkably, if any other gambling platform had the same huge house edge, its users would surely turn away and go to their competitors. But that wasn't the case with freebitcoin, as their multi-million audience didn't even notice the huge house edge for years. It's even hard to imagine how much profit freebitcoin was able to make from such a house edge.
