What will you do with your last balance? Waiting for the right moment before made a bet or because I like sports betting sometimes I bet on the game that will end? i do that because no more chance for me so i think better i'm rely on luck.
just like you I prefer to play by relying on luck rather than waiting for the right moment because usually the last balance contains little funds. so if I win not so much that I get and I also let go if lose.
