If I chose to start my career in gambling, then I would choose something that requires intellectual effort - either poker or sports betting. It seems to me that such an activity is less dangerous in terms of addiction, plus it makes sense, unlike slots where you just need to press a button. As for profitability, I would not count on it, first of all, this is entertainment, and a very small percentage of all gamblers win.
You have good self-control to avoid gambling addiction, soccer gambling is more precisely a hobby developed based on interest about football, then it can be increased for profitability on gambling platforms, but for slot games it seems unfair because it spends time only to lose.
Yes, I do not have a gambling addiction, and probably because I avoid options where you can get it. I have seen several examples of such addiction that have led to the destruction of people's lives and now I am very afraid of this. It seems to me that betting on football is a completely harmless entertainment, because those teams about which I have more or less information and can guess how they play do not have matches every day. Therefore, having made a bet, I always have a couple of days to distract myself from betting and thus do not become addicted to it.
