You shouldn't invest all your winnings at once, you should take 50 percent, and with rest you should gamble
Not a good idea i think if you gamble again the 50% there is high possibility that you will lose that amount.. better to spend it or treat someone that we can feel that we win the profit..
because if you are just saving them tomorrow or next week you can be still gamble and use the money and trying your luck again not everytime that you can win you will lose it all back again..
