You can use one of the slum as a prototype for bitcoin adoption and test if the awareness and usage performance should be scale to other parts of the country.
In the long run. At the start, I don't know how many bitcoiners would be willing to make a commitment to even congregate in one small neighborhood. It's a pretty bold move. There is strength in numbers. Taking over even a block in a rundown city could be effective. Next opening a bitcoin only bodega/convenience store on the corner is a first step I see in my imagination.
