It is a well known fact that Freebitco.in website has a really big house edge compared to other casinos but the players already know that,it is roughly 5% which can be considered a big one.The players though keep playing because they get other benefits for the money spent here,like lottery tickets,reward points and even Lambo tickets.They,the players already know that and no one is forcing them to play,of course this is a big part of the revenue of the Freebitco.in website.
