Are those "digital currencies" not using cryptography? If so, they're a cryptocurrency, regardless how centralized or not they are. See Tether for an example of a centralized "cryptocurrency" (not "digital currency").

By this logic buying something on Amazon in USD, or doing a bank transfer from a Wells Fargo account to a Bank of America account, or paying a water bill is using a cryptocurrency hahaha
Is that really the basis of those transfers, or something that they're using? This is why it's kind of tiresome to even mention cryptocurrencies/blockchain, all the "assume good intentions" and "answer charitable" suddenly flies out the window.
Why is it that some topics just triggers some raw emotional feelings in people?
Yes, when I worked with moving money between businesses and banks decades ago, we used public key crypto as part of the system for sharing ledgers and running transactions. Banks aren't stupid, any technology that can actually reduce fraud by more than the cost of using the system gets quickly adopted.
