I realize this question was probably raised before, but I believe that the answers might be changing with time, because bitcointalk community grows and because the interests and needs of people can become different in years. I recall a video on addiction that explained that people mainly become addicted because of feeling sad and lonely. When I made a thread about whether gamblers think that gambling addiction has the same reason, the answers differed a lot. Now I am curious what kind of people are gambling here. Are they mainly looking for money, excitement, socialization? Please vote and leave a comment below in case you want to add something to your answer.
I don't know if you seriously ask this but there is no key reason to do this or that. You do what you need, always, you do because you get pleasure from it or expect to get it. From casinos, you'll hear one reason: Have Fun. But it's the least reason people gamble, usually they are looking for easy money. Imagine you have 100$, one roll and you have 200, this happened in one second, pretty easy money yeah? Some people in poor countries have to work for one month to get that wage, you did it in second but you can also lose it so quickly even on first attempt. But since therevis possibility of win, it attracts people, it's their main inspiration. On another hand some people socialize as you say, for example communicating in chat, some people feel well when they tip others and they chat: thanks, you are amazing and etc.
