While 50 Million Ind+Nig+Kenyans having 100K wage would be a stretch, the 66% bachelor's degree isn't that unbelievable of a figure.
The 66% would have been meant that the rest of all bitcoin owners in the whole world would have definitely a bachelor's degree. That combined with statistics that show that only 30-40% of the western world holds a bachelor's degree, if we assume an 80% when it comes to crypto owners it would push up the percentage needed for Both Nigeria and India to over 88%.
Common, let's be realistic.
Bachelor's degrees aren't really that hard to come by in developing countries where there are Govt funded institutions that dole out degrees in humanities or commerce. Professional degrees maybe a little harder to come buy but almost every middle class person gets bachelor's degrees.
Statistics show only 27% of high school graduates going for a tertiary level of educations for India
So it's not like everyone is more like one quarter and this if we count young poeple, probably if we go in the 40-50 yo area this would drop to below 5%.
You can forget about this whole "Bitcoin will soon replace banks thing" until Bitcoin's technology is actually capable of doing this, which is not happening soon, maybe it won't ever happen. It's no secret that onchain capacity can't cover the daily need for transaction of even a small country, and even with Lightning Network, if everyone tried to open a channel, the backlog would be enormous.
The capacity is one problem, for now, but the other is the integration of services and a way to have this work on some blockchain, something that to me with bitcoin alone seems impossible.
People really think of banks just as cards and deposits, they ignore merchants, companies, and 99% of all businesses, for example, we have an open working capital credit line with our bank, if we somehow at the end of the month we don't get the money from our partners but we need to buy something or pay bills we have a 30 days grace period with zero interest up to 15% of our prior year revenue that we can use for emergencies.
How would that work with crypto and without a 3rd party?
