Addiction comes when you lose a little amount of money every day and winning a huge amount of money after a couple loss. that's where it starts it's based on our emotion. When we think that we're making a lot of money through gambling we think that we're actually always winning without thinking that we already lost a lot of money upon playing it everyday. in terms of playing recklessly it mostly comes after a you win some and you constantly losing that's where it starts because you wanna feel that excitement again that feeling of winning. So you tend to bet higher in order to get your loses.
That is why you should always not play when you're already high on your emotions because that is when you start thinking the opposite, meaning you aren't able to control yourself as you've just thought that you will keep winning or you've just wanted to chase more winnings because of your losses. No matter if you lose on a daily basis, if ever you've already won big time, or let's say winning 10 times in a row, that is where your emotions kick in, and that is the most dangerous part as you don't know how to stop betting that time and wanting more.
