Those are good points, especially the third one. Indeed, as surprising as it might be, Africa countries like Nigeria and Kenya are some of the top Bitcoin holders. Plus with the recent Jack Dorsey proposal of Bitcoin Development Trust for Africa and India, these regions will be able to benefit from cryptocurrencies and improve their economy even more.
However, I'm not sure about this one:
#1 BTC provides banking services to the unbanked Millions around the world who cannot qualify for a bank account use BTC to conduct business and make electronic transactions.
In order to use Bitcoin, you've got be able to afford a smartphone or a laptop, have enough funds to pay for recurrent high transaction fees, and if you have sufficient funds for that, you'll most certainly qualify for at least a few bank accounts in your country, IMO.
