I think it will be very hard to win on this game, From now I cannot see any lucky winners yet.
yea almost all of last bet users placed bet at near 40X, so its definitely hard, i would suggest users to place bet 2X or 4X, betting at 40X is recommended for small amount only !
its like you want to make 0.1 to 2 BTC its definitely gonna have lower win chance, but if you want to double your 0.1 to 0.2 BTC there is close to 49.5 % chance of doing that,
just like primedice yolodice or stake
