An African central bank is suspicious of cryptocurrency. How is that somehow evidence that wire transfers are difficult?
I guess if the use case is “I want to send $1M from Iran to an American who will distribute the money to Nigerian accounts”... Then yes, that is presumably easier to execute in crypto. But there are also pretty good reasons why countries want to keep an eye on that kind of flows.
I see you've never lived in an African country. Remittances of any kind, even between neighbouring countries, is slow, painful and depending on which country on the continent you're in may not arrive at all. I haven't lived in Asia, South America or even certain parts of Europe but I imagine you may find similar conditions there as well.
