Try gambling with a demo account. See if you still have the same novelty or if it wears off after some time just hitting numbers on a screen that don't mean anything. What do you say?
For me it would wear off very rapidly, I think it woul be more fun to give people money to bet so we can see their reactions and maybe change their lifes.
Not only I would do good by helping people, but it would be fun to watch. Just hoping I would not give someone a gambling addction based on free money for them to lose all and more later.

Why do soccer players who are paid high salaries and have a good life know that, regardless of whether they lose a game at the end of the month, the club will pay them a high salary. When they lose a game, they feel sad on the field?
They want fame also, of course. If it was for the money, Vini Jr would be in Saudi Arabia now getting $300 million per year.
They want better teams, awards, their name on the news, a baloon d'or.
