i'm having hard time to do this also, i always made profit but because i want more profit i continue to gamble until i lose all my balance, i cant stop playing, i only stop when my balance turns 0, reading all the comment here i learned something, will try to withdraw profit from now on .
just remind, dont be greedy. if you have already got profit you know when you stop to play it
dont to continue with expected get a huge profit. this is gambling with high risk to lose you all money.
True but I think it's very difficult to stop gambling. Perhaps so as not to lose our gamble was not in great numbers and only a quarter of a percent of the bitcoin we got.
