Yea I think Bitcoin has played a very vital role in the world at large not only in Nigeria,in Nigeria i think it helps in reducing the numbers of unemployment,in the sense that those who where not working in the government and they were able to engage themselves in cryptocurrency are doing very well and living comfortably without bothering for anything else about the government since the government didn't contained them,even those that are in the government too .

Bitcoin brought about another alternative means of becoming self employed as long as you are into BTC and you really have the skills and understanding memory you can do marvelously well..

It also helps int terms of devaluation of naira to dollars,if you are into cryptocurrency and you are favioured,i don't think you are affected by the naira depreciation..
