Many governments in Africa are finding it difficult to adopt bitcoin and talk of paying their workers in bitcoin. I don't even think that even countries that have adopted Bitcoin will plan on paying their workers in bitcoin. I don't really think it will make more sense for any government to be paying their workers in bitcoin. Due to the volatile nature of bitcoin, the price is always fluctuating, so if workers are paid in bitcoin, it will affect some workers because some of them may lose money in the bitcoin market, which is not stoppable.
 
And even in some countries, governments have to start paying their workers in bitcoin. I don't think it will start in African countries because I believe the rate of internet ignorance is very high, and if possible, any African country will start paying their workers; it will not be in this current generation, it will be in a generation with some level of ignorance in African countries.
 
In short, I don't think Bitcoin was created to replace fiat money; it was created for the purpose of privacy, and I am sure people's privacy is what governments don't really want, so I think it will be so hard for the government to pay workers in bitcoin.
