Playing dice is easy and if it's one of the first games to ever launch after the bitcoin, satoshi dice was the first one? or was there some other dice site that came before it.
In any case, your winning is good and I think you did great if you pressed withdraw button after those winnings.
That is why many people try and continue playing dice games as they want to win dice games.
@OP winning that much money and he deserves that but he needs to calm down his mind after that is winning and maybe enjoying his winning for a while with his friends or himself will be better to reduce the tension after winning.
Withdrawing the most money from the winning will be better and not saving big money in his gambling account to prevent him from continuing playing the other games and testing his next luck.
Congratulations @OP, I hope you can win the other gambling games.
