Bitcoin and cryptocurrencies are an excellent choice for countries that are constantly experiencing macroeconomic problems and facing the reality of inflation. In this respect, the African continent is also a very suitable location for this new technology. Also, access to financial services in Africa is quite limited (just like in El Salvador), but we have yet to read any remarkable news about the mass adoption of cryptocurrencies in Africa.
News about the adoption of cryptocurrencies in Africa has actually been circulating and has been in several media, it's just that there is nothing recent like the one made this month, but for the news in the previous month it has been promoted more by the media. This means that Africa already has very good plans for the adoption of Bitcoin and cryptocurrencies and is working to make that happen over time.
I think, issues such as volatility, legal regulation and financial literacy may be an obstacle for the masses to prefer Bitcoin for now, but I am sure that the countries that take these courageous steps will one day be remembered with respect.
Some of the obstacles that you mention are indeed very reasonable so that the state must continue to strive to make other better ways so that it is no longer hampered by volatility, legal regulation, and financial literacy. Because of all that there will be more solutions if more people are willing to think about it in order to achieve the goal of mass adoption of Bitcoin and cryptocurrencies. After all it also includes the economic sector that is better for all of them.
