If there's one thing we know about the Nigeria Government, it's that they hardly want to be left out behind when Western World moves, even if they come late to the party. That that's why I strongly believe that in the nearest future, Nigeria may adopt a Bitcoin Reserve Strategy like the US and few other countries are already doing.
They will have no option than to follow what is going on. More countries will likely have bitcoin in their national reserve and Nigeria will one day consider that.
But we need youths that are crypto enthusiasts and crypto enthusiasts to be in politics and power because this can hasten it.
About where you posted that fintech may later integrate bitcoin and make it available on their platform, I think we still have a long way to go because the our government will still see it as an asset competing with naira and not allow that. Although, bitcoin is not a replacement and cannot compete with naira.
I quite agree with your submission about the fintechs in Nigeria integrating Bitcoin on their platforms and that's why it's a future "projection". However, we have to understand that the moment the federal government of Nigeria officially joins other top nations of the world to invest in Bitcoin, it'll automatically give birth to widespread adoption of Bitcoin by different institutions in the country and for fintech platforms, integrating Bitcoin into their apps will be easiest way to keep in touch with the development as well as keeping their customers who would prefer seeking alternatives to join the Bitcoin movement if they aren't getting the features in the fintech apps.
As a developing country trying to join build a strong economy, Nigeria government in no distant time will definitely join the other globally powerful economies of the world to invest in Bitcoin. That I'm very much convinced will happen.
