> The "unbanked". This is the market Ethereum wants to serve

M-Pesa got there first, and without the taint of cryptocurrency. It's a real, deployed, working system at scale, and has been for years. The idea that a "hope to serve" after a bit more crypto tech innovation will open an untapped market ... well, I wouldn't take it seriously. It's wishful thinking at both ends of the supply and demand equation.
