Due to the spot congressmen occupy I think they should talk about bitcoin seriously instead of only attempting to farm likes and shares. What important project is he talking about? How will it work on practice? What does a bitcoin adoption project has to do with a picture of the congressman displaying laser eyes? We need more seriouness... Let the jokes and the catchphrases for the clown Elon Musk.
We can't really answer what projects are in the horizon, so your questions cannot be answered by this time. So let us give them some time, El Salvador, Paraguay and maybe neighboring countries will follow as well. And I will assume that he is all serious because he represent his country, and his tweet coincidence with the recent bitcoin conference wherein he is an attendee if I got it right.
If bitcoin can help these people finding online opportunities it will be already a wonderful help for their local economies development. However, it can happen only through a serious and dedicated approach from the government to its citizens.
