I think the reason for my belief about iPhones-in-Nigeria being a small market is self-evident. As for other examples: people tend to buy things locally because local businesses are generally good at recognizing local demand, organizing import if necessary, and reaping the benefits of scale (shipping a container of phones). That this arrangement allows for localization of the product which further increases local demand is just icing on the cake.

Yes, but they are getting bank or quasibank accounts faster than they are getting Bitcoin wallets.
> Would you really say no to saving $100 when buying a new MacBook?
No - but as a price-sensitive customer I would buy a couple-months-old, gently-used Macbook and save $200 or more. As a price-sensitive business I would buy a Dell.
> A fringe here and a fringe there and pretty soon you have a whole robe.
Sure. But a robe still much smaller than a mainstream provider like Visa.
