Most people gamble due to greed and think money earning is easy, in gambling we gain some profit initially but finally end with losses. It is a easy way to loose money.
Gambling is indeed one of the easiest ways to both win and loose money since people will be greedy enough to think that they'll be able to get rich in not time at all and with a ridiculous investment of 10 dollars all of this without even moving a step forward , if you just analyze this behavior it'll completely seem nonsense and yet people still prefer taking this path over earning their money with their degree or sweat .
Gambling should be only for fun and whoever thinks that he'll become rich out of it is just fooling himself .
