Gambling is something you put money or bet in to a game, it might be small or big.
I enter to real casino once it is so addicting even I loss sometimes in my bets still I find it so entertaining which makes me feel happy despite the fact that i loss my money. Maybe the thing that we need to set up in to our mind is put bet what you can afford to lose.
But there are people who treat gambling as their business because they know how to play the game, the tricks and techniques, but most it is for their entertainment.
Gambling is the root of addiction because when you start playing and when you encounter a winning streak, it will drives you to play even more until the time that this game will be a part of your system and you couldn't imagine to live without gambling that's why I never tried to play gambling for the longest time. I tried to play gambling for just a short period of time before but I never tried again because I'm afraid to be addicted on games like that.
