it is wrong if you consider it anything more than a hobby, you can't make stable profit from it and you shouldn't spend too much time on it, Also never use big amounts in it IMO.
I agree with you. if we look at gambling as a source of income was very wrong. but if it's a hobby or having fun its good. because if you consider it as a source of income you will be addicted and could also lose all your money and also can make you crazy.
