I completely beleive the site have the ratio of winning lesser than common betting site. I have played bitsler, stake and some around gambling site so i know that. In this "multiply game" of freebitco.in site, you should not playing this kind of game. Unless you have the suitable stragety or the purpose for doing this and you know what you are doing. Otherwise, best thing you could do is free roll and upgrade is the best profit as i know! Don't gamble if you dont know much about it. Really! And one more, the streak of losing of your 2.5 ratio is common, even it should be last longer to win the round. You should not complain about it! Its common. Bad lucky to you. Sympathy with you! Hope you understand it
