This is a very great development for Nigeria, because the way cryptocurrency go viral in the entire world, countries that are under develop or develop countries. Cryptocurrency help in the development of country because cryptocurrency is an advance technology so countries willing to develop or advance need digital currency for trading and exchange of good and services. So for Nigeria as a country to launch cryptocurrency is a good development for the country.
The country is one step ahead at this time, they are able to see the times with the discovery of new ways to maintain the viability of fiat currency, countries like this are usually in good condition, so it is necessary to create digital currencies to keep the country's economy more stable, Cryptocurrencies can also applied in general practice in a country, if the existing resources can be used properly, this will have a big impact if the country makes binding rules.
But I don't think they will be accepting cryptocurrency, it is more of developing their own digital currency so they still have full control about its circulation. But if nothing else, once they launched this digital currency, their citizens will be oriented on how digital currency works and so it may pave the way on learning how to use crypto. Maybe this is why they ban crypto because they have plans of creating their own digital currency.
