Personally I don't really understand everything you said here but I will try to put it in my own words.

Are you suggesting our government should make cryptocurrency legal in the country? for it then to work side by side with the fiat because aside this there is absolutely no way the cryptocurrency can collaborate with fiat.

The only way the government can help Nigeria for me ooh, is by pulling out from this system of government or even the entire leaders step down from their position let the people choose who they want and how they want it.
