I think the article is very correct.
Poker, online or not, has a bad fame. The common image of the game for those who never play it, is a bunch of people smoking, drinking and losing their houses at the tables.
In fact, I think most of players are just looking for fun.
There are addicted of course, some for
gambling, some for the game itself. They have the kind of personality that tends to addiction.
I saw people addicted to poker as I saw for Candy Crush, Dota or Counter Strike. They love the challenge, the opportunity to prove themselves.
And I always see gamblers who are addicted to risk money and lose the rent money or even spending all their salary in one night. For these people, the game they play doesn't matter in fact. It could be slot machines, sports bets, or any kind of thing that promises a chance of big winnings.
Poker rooms have games for these players.
spin and go's, hyper knockout, aleatory prizes, all the kind of things addicted in gambling loves. I try to avoid those.
