Dont know what has changed in the recent few weeks but i personally have withdrawn around 1.8 btc from freebitco i love the site its fun and profitable however the past few weeks i have done nothing but lose literally every stratagy i used to build up my 1.8 has left my balance 0.00000000 :-( ive lost around 0.3 now sure it could just be bad luck but it feels like its on purpose i even put it on 1.01 and lost loads of rolls like wtf is going on dont think its worth the multiply game something has defo changed stick to the free rolls people :-) or lose everything u have
To be frank i am really surprised to see someone win this big with the rolls in the site as i have not heard about this from anyone,you are just a lucky individual to win this big as the house edge they have is much bigger than rest of the traditional dice sites and be happy with what you have fun and take a break before loosing everything back. 
Yeah i am happy with what ive won im not a greedy person, but from the start i know no game is fair they dont have games like this for everyone to win thats not the point, so as i played i noticed its like the game is learning how i play for example if i rolled in a certain sequence that made me win eventually it would make me loose every time no matter what the difficulty or bet, like the 1.5 difficulty for example when i won on high it would normally be high again i won about half a bitcoin doing that but now no matter what i do manual or auto i lose it all
