In different occasions of economic crisis in the world bitcoin has always been there to play a good role. Thanks to bitcoin for it existence in this difficult time of life.
Nigeria banks were ban Bitcoin, so it's illegal if you use Bitcoin, you might not have any problem now but you can't predict the future.
You need to have money if you want to buy Bitcoin, Bitcoin was not created to make people rich and solve the economic crisis. More importantly you need to have electricity and internet connections, most of poor people can't afford it.
