Woohooo didn't know Marlon Vera become a Roobet brand ambassador, it would be better if Roobet can reach Oliveira or McGregor since they're very popular on UFC.
I don't really follow the UFC, so I don't really understand how popular Marlon Vera is but compared to McGregor people will be more aware of McGregor and it could be that his level of popularity makes Casino have to spend more to sign him become a brand ambassador, but it could be also that Roobet is targeting the Latin America market to be able to get a lot of players from there.
