Hence with 1.7 billion people staying unbanked, added to the increase of people who don't rely on banks, Bitcoin provides them with numerous options why they should use bitcoin for different purposes like sending money to relatives in different countries at a very low fee.
These are good stats. I love reading publications that have a positive "feeling and attitude" towards Bitcoin. It gives us hope. However, the problem I have with people quoting numbers and drawing conclusions is that these data and analysis may have been gotten from a secondary source.
I live in Nigeria and I'll tell you for free that despite our population of over 200m people and the number of those unbanned it an illusion to think that Bitcoin and bank the unbanked. The unbanked are the uneducated at the high school level. They are those living in rural areas without electricity, no English , good roads, portable water, and internet connectivity.
For Bitcoin to bank the unbanked, these barriers need to be fixed. Realistically speaking, I don't think Bitcoin can do this.
