Gambling is addicting because it is a way for you to earn money without any skills required. Unlike other methods of earning money, you need to have qualification and knowledge, gambling dont. However, they dont want to know that gambling also make you lose instead of win.
That is one reason but I think people love the risk too and they like to take a risk and come on top of it, for example in trading you can lose your money too but with the right knowledge you can make money out of it and when you win you feel a rush of satisfaction.
No, the people like easy money, without doing any hard work they need money, In this world, i think the Gambling is the only method we can make money without doing any work. That is why people are addicted to this gambling. And one more thing the Bitcoin price, this is also one of the reasons people are get addicting to gambling.
I never denied that was one of the reason and maybe even the biggest reason I just stated the are more reasons than just pure greed, some people like the risk associated with it, that is why there are extreme sports.
