I don't think any kind of gambling to be profitable in the long term, people can not win every time and sometime they will loose their money, so its better to play for fun and stay away from gambling addiction.
It is really better, but majority of those persons who play gambling only for money, including me because many time i play gambling for earn money, but still i know many chances to lose.
I also think that every game of gambling is not profitable in a long term, and i think it would be know everyone who play gambling.
that's how an addicted gambler play , they know they will lost but keep going.
and this is remind me on how important to set your losing limit amount .
so even there is low chance for you to get profit in the long term at least you did not losing too much.
So maybe I can call myself addicted in the past because that's how I play, I usually chase my bets because I am deeply saddened seeing my money slowly diminishing. But to tell you guys, it's not really good based on experience as it almost ruin my life, let's try to sleep even with big loses.
