Gambling only becomes a threat if you don't play within your means.
If you know you're the type of person who can't stick to a budget, then gambling becomes a threat.
If you borrow money just so you can play, then gambling becomes a threat.
It is easier in theory.Even for me who have been strictly following my monthly bankroll there has been times like this month that I won a bit of money in slots and I thought why not play to get that 10.000x bet which led me to losing not only my won amount but also a lot of unplanned money.
That's most likely will happen if we are weak in controlling your emotion, you got greedy when you win and when you lose as well that's why you lose your discipline, but you should learn from that as its normal for gamblers to make mistakes.
Bottom line is no one can really control their emotions so gambling can become from fun to threat in an instant.
I disagree with this, maybe there are people or a lot of people can't control their emotion but I'm sure there are gamblers who are discipline enough to control their emotion and stay responsible while gambling.
