Earlier quoted context omitted.
Are virtual currencies actually being used as currencies? I've been long BTC for ~10 years, I've only made a few small novelty purchases through BTC. Based on any ads I've seen for crypto from coinbase, along with the tools they've built into their app - the primary use case for crypto appears to be as a security.
i run a small retail shop that sells digital goods for btc. i bought a book with btc two months ago. more convincingly, it's widely used for remittances and as a store of value in countries with debased currencies -- this is a powerful tool for ordinary citizens in countries like venezuela, argentina etc to discipline central banks who would otherwise steal their savings.
Yet it would be absurd to call those toys "A currency". A currency requires more usage than occasional barter.
