Maybe journalism? At least not the entertainment news media outlets. It might be beneficial to hard-hitting news, but I'm not sure if it will be a good thing for the newspaper and the people.
The economy and finance related to the journalism and the media entertainment can be updated to the cryptocurrency wing for convenience and this might also boost the profit that is normally earned using fiat for this purpose.
In addition to industries like the Journalism, I believe that the undocumented industries and economies cannot be improved using this mood of transaction. This is just because majority of them are too illegal to be documented and cannot be covered by the cryptocurrency.
