Every thing remains good if we use it moderately but if we will start access use it can harm us and we can become addicted thats why we should use gambling but in limit and try not to be affected as a gambling addicted spend limited time in gambling and spend other for other activities. When you think you can control yourself only then jump in gambling.
It will be a must , we need to put everything in moderation , I experienced it myself,last year I gamble and I've lose to many money, I push myself to get back what I already been lost ,but it only worsten the situation , gladly I did not end up being an addict, because I still have a control in every game and in every budget that I have.
