Bitcoin fees are too high and confirmation time too long for most people in any African country. The short answer is they might accept is as a method of payment like Japan did, or banks may opt to use it as a background service, but its a long way off from being accepted as a primary currency
We are all basically in the same conditions
And while I agree in general that Bitcoin fees may be way too high for the majority of African population, the confirmation times are essentially the same for everyone across the globe (provided the fees are the same, of course), so it is certainly not about just for "people in any African country". In other words, it is for other countries too. On the other hand, Bitcoin is not the only pebble on the beach, anyway. There are cheaper coins with faster confirmation times and lower fees, for example, Litecoin (which has been on the rise recently)
I was thinking about it recently. If most people, not only African people, but people in the world in general, are only starting to realize the advantages of Bitcoin compared to fiat, how long will it take to realize the advantages of any other crypto compared to Bitcoin?
I think most people rather will come to terms with that 300-400 satoshis/byte fee and will stick to Bitcoin in the foreseeable future.
