It's natural for the people to get attracted to something big like a successful and diverse project. If a person, say, bets on his favorite soccer team, through ads he can get familiar with other sports and so on.
I think that those sports for which more bets are made automatically can become more popular, everything is interconnected
Interconnectivity is provided by this project. Everything else is the matter of whether people can actually get behind new sports as they crop up.
