Anecdotally, as a European, I have always been confused by people advocating the advantages of cryptocurrency by saying that ordinary bank transfers can take 3—5+ days to reach their destination, or that bank transfer fees are $25 or more. It always sounded strange to me, as I can make a free next-business-day (or even same–day if I do it early) bank transfer in euros to any bank account within the Single Euro Payments Area (~= EU+EFTA), and the fee is €0.00.
