I think the reason why they are getting addicted to gambling is just because they want an instant money, they want an easy profit which is not possible. Beside, I think another reason is once they play gambling and lose they tend to play again to retrieve their loss then it'll become habit of them which can conclude that you became an addict.
Instant money is the biggest lure for people due to which everyone tries their luck in gambling. Some are sensible and if they know it is not going to be easy to win from gambling move away or just play for fun and other who cannot control them self help the casinos owners to make them money as they keep losing normally and still anticipate of winning big and continue playing it.
Right.It's the big amount of money that always make the people developed interest on it.Because they believe that through gambling,they can have an instant money but of course,they can lose them in an instant too.So it's always been the greed of people that always lead them to their worst situation.Gambling is not that bad but if you don't have self-control,then it will really ruin your life in the long run.
