We are talking about a country that tried to ban internet and computer (three decades ago). So it is not surprising that they are trying to ban cryptocurrency. And from what I have heard, as a first step they have blocked the IP addresses of various online wallets and cryptocurrency exchanges. These idiots don't even know that blocking IPs don't work nowadays. Anyone can access these sites using a VPN or a web proxy.
unfortunately in africa things like decentralization are a big problem for governments, because in africa the political parties that were responsible for freeing the countries from colonialism deceive the people with things like: patriotism, sovereignty and culture, when in fact they do not belong to the government they are patriots and all they have are things imported from other European and American countries, for example: African leaders import wines in their homes, but they keep telling the population that they should just like to consume the wine produced in Africa
African governments are afraid of bitcoin, I will give you an example:
In Africa, governments are able to control opposition parties by giving them little money for the election campaign
imagine if an opposition party invests in bitcoin and then gets a lot of money? this could make the opposition party win the elections, African governments know about this danger and need to control everyone to stay in power
Not only Nigerian but many other countries are also hostile to cryptocurrencies.
countries where democracy and freedoms are restricted are where bitcoin is not welcome
