Looks interesting on a light skim. However, one key point that is always missing, how will people buy/cash-out this libra currency? Most developing countries have transactions going on in cash(unless it is happening in few hundred thousands). You'd be lucky if you see a card-payment machine anywhere except on exotic shops like car-dealership/real-estate/big brand electronics(apple). ATMs are for rich/wealthy class only. There are no debit cards, banks don't give out credit cards to anyone unless they have HUGE middle-class+ transactions/income in bank history. So, how are people going to use these fancy currencies? I have lived and visited developing countries, no paypal, no credit-card, no debit card, no bank transfer, only paper-bills accepted :)
