OP I see you are a newbie here. It is nice you initiated a topic of discussion unlike back then when we came on board, it took us a little time before we could start creating a thread to start a topic or commenting and looking at the numerous things we need to learn and getting knowledge about here but notwithstanding, learning is a gradual process which one needs to undergo before perfection. But however, what you have asked here is very much important though.

Nigerian  government I think would not buy into the idea of making Bitcoin a national currency but I believe it would be accepted as an alternative in the sense that it could serve as an alternative means of payment between customers, businesses, and others as a digital currency and would be raking in revenue from transactions involving bitcoin payments and deals. Nigeria's government so far has been of the opinion of making her national currency more strengthened and valuable so therefore anything that would alter her course would be strongly opposed. Have you not heard of the news of the Bureau de Change calling on the federal government to ban Binance that has nothing to do with our currency devaluation?

The economy of a nation does not really depends on its currency but on what policies they have put in place to strengthen the economic and bilateral trading relationship with other foreign nations. What does a country have to offer to the world in terms of production and export? Being a consuming nation adds no value to her economy and currency so therefore  even if bitcoin is accepted as an alternative currency, it has no effect on the economy instead  her citizens would opt for it as a store of value to do away with her currency devaluation and economic inflation.
