Technology-wise, most countries have faster methods of sending money than how US system works: FedNow is a very late welcome addition that analogous systems already exist in other countries for years, even in places where you don't expect (Nigeria, Myanmar and India of all places do have near real-time transactions).

It doesn't help that their government tends to block improvements that will go to their citizens and just plunder their countries' resources. What problems does cryptocurrency solve here?
