After you have won you want to do it again and again to earn money but this is of course not gonna happen it only will be enjoyable.
For people who thinks it's a way of earning fast money it will lead them to loosing big amount instead. If you treat it like this then you won't gonna get any profit at all, it will just make you chasing your losses. Greed is the most common causes on why many gamblers get addicted and loosing big amount money.
I find it right, being greedy is one of the reason why gambling is very addictive. Because you have the chance of winning high amount.
But the chance of losing also is high. And people who wants to get shortcut in riches will take the risk of gambling.
After which, if we are still believing that we can win although we have proven with our losing record that it is impossible then I would call it stupidity and being stupid in gambling is a serious disease as it might end up wrecking our life.
