Your reasoning seem to be based on a very wrong assumption that people from poorer countries, or sending to poorer countries would not buy BTC with dollars or euro. Just for starters, USD is the first currency of choice for major (relative to relevant economy, buying a small fridge can fall in such category) operations in such regions, with EUR being second. Inhabitants of poorer countries do a lot of cash transactions in USD, EUR, and I'm not even sure what do you mean by "access to USD" in such context. And majority of those shadowed migrant remittances comes from US/EU, not vice versa. So there's no inflow in Zimbabwean dollars, and many other unstable currencies because they are unsuitable, at times to the point of being useless.
