I asked the following questions at meet-ups in Kenya and Nigeria:
Who gets paid in crypto?
-> 80% of people raised their hand
Who gets paid in local currency?
-> 5% of people raised their hand
Who prefers crypto (btc, eth, et al) over stable coins?
-> 2-5 people raised their hand
Who prefers stable coins (USDT, not USDC) over crypto assets?
-> 95% of people raised their hands
Who is using binance p2p market place?
-> everyone raised this hands
Conclusion: Locals want access to US dollars and the crypto rails provide a very convenient / easy path to access it.
