The Central Africa Republic (CAR) is bordered by:

• Chad, Cameroon, and Republic of the Congo - Brazzaville, which use the Central African CFA franc ($XAF)
• DR Congo - Kinshasa, which uses the Congolese franc ($CDF)
• Sudan, which uses the Sudanese Pound ($SDG)
• South Sudan, which uses the South Sudanese Pound ($SSP)

So presumably then this will give reason for the foreign currency exchange bureaus in each of these bordering countries to support bitcoin as a currency they offer to exchange.
