the main obstacle of all of that is the factor of poor technological resources. there is no internet network in most of the african countries. banks can grow because people don't need the internet to save money, but bitcoin needs a lot of resources that are not owned by many people there
Lol, I guess you don’t know Africa too well or you have never even visited any part of Africa that much, Google it yourself, you will see the high rate of internet usage in Nigeria, and if they all know and keen about technology also, you will know that crypto is nothing to them. Look at the smart phones that we use.
Aside the apple that the Americans are all crazy about, Africans are the ones that uses these smart phones more, and reason for holding these sophisticated smart phones is mainly to be able to browse the internet well through it and see some technologies through some software’s that is need to be downloaded through the internet,. Don’t under rate Africa when it comes to cryptocurrency because the acceptance there also is becoming high.
