the worst mistake i made is greedy. play again and again after winning. and at the end i lost
Worst mistake to me that anyone can make, is to believe that he will win or will continue winning, or after losing believing in revenge that he will have to win back what he has lost by still gamble because with that you will be guided by subjectivity rather than objectivity and that's is the major or worst mistake to make in gambling... My 2 cents...
