For me gambling isn't wrong because it is part of our life today. Many people use gambling as their source of income. Many people became rich because of gambling. In my experienced since I was started using bitcoin I started to have a small business that gives me some extra income. And now I used to play gambling again so that  i have my source of income. Gambling isn't bad if you didn't able to get addicted. But yes, if your greediness overcome you. And you are being addicted to it. That's is why gambling is bad or wrong.
