If you have an addicted personality, anything can be addicting. Alcohol, drugs, sex and etc. So yes for some folks it can be. I'm pretty sure I am, but not to the point of losing money. Just playing everyday.
Yes maybe. Like any other activity. But the main thing is to play wisely and by bankroll.
Hello.
I think disciplined players will never be addicted to the game. Although, it all depends on the character, willpower, and goals of each individual.
