I don't know if the government of any African country have adopted the system of paying salaries in Bitcoin,
No African country has announced the full adoption of Bitcoin as legal tender aside the central Africa republic who is the only country in Africa that have adopted Bitcoin as an alternative and even at that, they have not made it known whether or not Bitcoin is used as an official currency for workers salaries, although we already are aware of the sceptical nature of many governments towards bitcoin and many of the countries have been on attacking mode and the majority give a red light to Bitcoin adoption.
So for that, we are still far from achieving that state where an African country will adopt Bitcoin to pay salary, and not even El Salvador who was the first country to adopt Bitcoin has not implemented that law in its system yet.
Even Central Africa Republic adoption of bitcoin too is in low key because after the announcement of their adoption of bitcoin as their legal tender, I have not heard anything from them again. Or is it that they not much in this forum? Because I have not even seen their posts in the forum. And if really African countries accept bitcoin and using it to pay salary then the inflation level would come down because the use of local currency will reduce and one the uses of local currency is reduced then the demand of dollar rate in the continent will also reduces them dollar will fall out from the continent.
Accepting bitcoin in all sectors of the governmental institutions is what we are hoping to see and do in the region we are really tired of the high inflation in the continent.
