I don’t think the issues with traditional currency being lack of transparency with financial institutions and inflation is much of the issues here to have lead to more and more crypto adoption.
I think cryptocurrency adoption has been about having an alternative to traditional means of finance, the privacy it provides, the ease of having to send funds across time and space in an instant, less fee and having little need to worry about the government. This is just but a few but yeah, it goes far beyond those reason as stated in the first instance.
Talking about Nigeria, I agree that the government have failed its people and you have everyone looking out for a means to survive, some of those means are found in Bitcoin but yeah, it’s by far means to transact and survive in a nation where majority of the population are below the middle class and not employed.
