“Crypto solves this” Does it? Transaction times and transaction fees on some of the more well-known cryptocurrencies would seem to exclude them entirely. There’s no particular reason that it has to be a decentralised cryptocurrency that operates in the manner required - preloading a few bucks here and there, which are transferred between accounts in small amounts. As with many things that “crypto” solves, it is neither necessary nor sufficient. Some cryptocurrencies could form part of a solution. It’s not clear they bring any specific advantages to the table though.
