was just wondering if someone here has win some btc on the lottery
playing it since 6 months and never win any lotto, i'm starting to think that the adm manipulate the whole system

If you won even in small amounts on that six months then this should be normal. If youre aiming for the jackpot price then you should buy more than five tickets per day and if youre lucky, you can win the jackpot in a year, if not then dont blame the site whether it was manipulater or not. If the house always gives away jackpot then it will be bankrupt in a month.
It is clear that he OP mentioned about 6 months of playing and never got a single win,thats why he was thinking of some manipulation happening in freebitco.io
Though I never tried to play since I dont believe in freebies of some gambling sites here.sorry but thats what my thoughts about it
