In African countries, I am a little hesitant because there are so many cases like ICOs that fail and there are many other cases that use cryptocurrency, so in Africa it is not necessarily a good place for cryptocurrency so you should stay alert when saving your cryptocurrency.
The economy of the country is not as good as that in Europe or in Asia, so in my opinion, if there are many cases that occur in Africa about a lot of ico who have failed, it is a natural thing.
