You will become addictive once you experienced the so-called "beginner's luck" or early big-win. But then after that, you will try to re-coup what you have lost and ended up an addict.
Not really if you know what you are doing since the beginning and you tried gambling first time with a long term commitment in your mind. So you already have a plan what you will do (I am talking about sports betting) and you will put aside a monthly bankroll and play only with it. If you go out of the borders ,addiction is all you will get and it will bad for your money and health.
That is so silly statement right there, gambling is not a needs that you should consider to put in some amount every month . One thing for sure you are going to lose most of the time so there isnt any need for you to spend a fixed amount every month to throw into one of those gambling sites, even if you win in the end you will lose just alot more
