I have listened to a few hours of Prof Steve Keen and I acknowledge his model which determined that personal debt is the driving force (at least highly correlated) with the ebbs and flows of the economy. I am less convinced of his opinion of Bitcoin (or the technology) not being money. I am not sure if it really matters. Money is an intermediary token which aids in the exchange of goods and services. I have bought stuff using cryptos ... I spent an afternoon buying people coffees at a little cafe to demonstrate the simplicity of doing so. If that isn't a form of currency, I don't know what is.
