A few years ago my company had to get US dollars out of Nigeria from the sale of the products we manufactured to pay the suppliers we have in other countries.

A few years ago my company had to get US dollars out of Nigeria from the sale of the products we manufactured to pay the suppliers we have in other countries. Perfectly legitimate reason, but due to currency restrictions in Nigeria the finance guys had to use a scheme using a mix of crypto currencies (mostly bitcoin, I think, but not only). I don't know the cost of the transaction, but we barely covered it from the sales. I heard there was a similar problem in Egypt, no idea if and how it was solved.
