The thing is though, digital cash doesn't necessarily have to be cryptocurrencies, i.e. they don't need to go through the trouble of creating their own coins and then fight another battle to get everyone to adopt it. Wouldn't it just be easier if they put more stress on moving people away from cash and towards digital payments? I mean, digital cash wise, we're already using it, from wire payments to plastic cards etc etc. And if you add cryptos to the mix then you have the issue of getting everyone on board a system that is more nuanced and difficult to adopt that plastic credit/debit cards...
