And with the increasing loss in gambling person get more and more addicted because he wants to win his loss back as soon as possible and the more he chases the quicker he losses his money. That is a fact !
I think it's not "addicted" but it's "Greediness", when you're keep losing and losing, you always increase your bet and you hope you can get all of your loses + profit in a next bet. This is just normal thing in gambling, just go to 1 casino/gambling site, and you'll find a person who like this.
