bitcoin is a future digital currency, i strongly believes that before BTC celebrate 50 years in existence at least one or two African countries is going to legalis it. because block chain network is expanding every day by day. and most of the countries in Africa have the knowledge BTC how it works.
Bitcoin is already legalized in some Africa countries. I don't know the country that you are from, but my country has legalized the used of cryptocurrency, and Nigeria has the highest number of crypto daily users and adopters.
Nigeria, South Africa, Morocco, Ghana and Kenya and many more countries in Africa that bitcoin is legalized. It is not compulsory that the government must use it as a legal tender before, bitcoin can be used or is legal.
It is truly extraordinary that your country has accepted BTC in all respects and legalized it, because many countries hope for the legality of BTC itself, but it would be better if BTC was not used as the main means of payment because wherever fiat is the typical currency of a country, it would be very unfortunate if must be secondary in every financial transaction
