Facebook has sold its cryptocurrency as an opportunity to help the unbanked, the approximately 1.7 billion people globally that don’t have direct access to financial institutions. In an interview on Thursday, Sen. Brown told Cheddar, “When Facebook wants to sound altruistic, they talk about helping the unbanked and all this. But this is about more market. It’s about more money. Facebook sends its lobbyists all over Capitol Hill, but nobody really quite understands how this is going to work.”
