Isn't you guys have been using Bitcoin via P2P because your government have banning/restrict banks to be involved with sources came from Bitcoin? so I'm not sure why you have to bring a same discussion which you guys have doing since few years ago.
I checked on Google inflation in Nigeria is currently over 20%. This is practically a hidden tax, or a silent theft. If you simply hold and save Nigerian Naira, you lose about 20% of its value annually, which means you are, in a way, paying a tax.
That's actually the of Bitcoin's return, if Bitcoin double our money after 4 years, Naira make your money in half after 4 years.
