Some of what you say here is true but that doesnt mean gambling will ruin your life. If you have an addictive personality and cannot control when to stop gambling, then yes you prob shouldnt gamble. If you have self control and just wanna toss a few dollars around here n there then youll be fine.
Yes, that's right. We heard a lot of stories how gambling ruined somebody's life. And that is just horrible. but I think everything depends from concrete person. For example my boyfriend also likes poker and slot machines games (he plays it online), but we never had any big problem if he looses. He is playing with bitcoin only that he gets from commenting. So we never loose money from our salaries or something like that.
