Looks like a terrific idea! Have you ever thought about making it into a podcast of some sort? Like you and your friends sitting together (or remotely) and discussing books on Bitcoin, and all that will be revolving around policies in Nigeria?
And I like that you have huge plans to expand and to bring bitcoin knowledge across the city (and maybe potentially the country?).
Also, love the name - Bitcoin Tribe Book Club. Sounds pretty cool IMHO.
