To clarify, I am counting on the social network effect.<p>One person has several social connections, at church, work, gym and so on.<p>Your contacts have their own contacts and so on.<p>At some point, this network crosses borders. Being a country with so many migrants, this happens real close to you at USA.<p>If a Brazilian living in USA wants to talk to his family or friends in Brazil, he must use the same channel everybody here uses (or he will felt excluded).<p>I don&#x27;t know the numbers, but this can indeed happen with WeChat, but I think whatts is used in more countries.
