Welcome friend; you have come to the right place. You just completed the 21 Days of Bitcoin course; are you aware that there is a 21-day Africa Bitcoiners course as well, based out of Nigeria? Here is a link to both their website and Twitter page:

Even though I live in the US, I took the course earlier this month and it had a some content that was more centered toward an African audience, so you may find that helpful. Also, consider exploring these educational resources as well:

https://lookingglasseducation.com/ = Another slightly higher-level quiz to gauge your level of Bitcoin understanding; Look for the "50 Questions To Test Your Bitcoin Knowledge" under the courses section after you register for an account

https://bitcoin.rocks/ = A website with short articles about various aspects of Bitcoin; they will even give you a template to print stickers for international regions to help you spread the word about Bitcoin...or for you just to put up in your room as conversation starters

https://www.2minutebitcoin.org/ = Just like the name implies, some good short articles about bitcoin and bitcoin history

https://bitcoinmagazine.com/ = A pretty good source of current bitcoin news. You can also earn/stack sats by reading articles in their app. Of note, Bitcoin Magazine has a great guides section (https://bitcoinmagazine.com/guides) that summarizes big picture topics around Bitcoin

Glad you are here and look forward to learning with you and from you.
