what fraction of Africans have a smartphone? why, for those with a smartphone, wouldn't they just log into citibank.com or whatever, instead of a bitcoin block

what fraction of Africans have a smartphone? why, for those with a smartphone, wouldn't they just log into citibank.com or whatever, instead of a bitcoin blockchain app? There's nothing inexpensive about bitcoin, in the big picture. you seem to only be hoping that the organizations running the electricity into servers are providing free or super cheap banking to users, i.e., they're eating the massive expense of bitcoin over, say, hosting MySQL on trhifty digital ocean or azure or aws. is that correct understanding of what you mean? How is bitcoin a hard asset? > many Africans are already investing in Bitcoin. do you have a citation for that assertion? i have not found one.
