Regardless of how you feel about crypto - and I admit to seeing some valuable use-cases, while being highly skeptical of the speculation - you gotta admit that these comments are prescient and also very funny. I sincerely hope I have that presence of mind at that age.
FedNow aims to provide *instant* and secure transfers between existing fiat bank accounts 24/7/365 at a projected cost of 5 cents per transaction. In trials now, scheduled to launch in mid-2023. The most valuable use-case for crypto was prodding the Fed to develop and implement this. If all goes as planned, consider crypto's work done. https://explore.fednow.org
Also fednow does not work outside the US currency system. You can not send USD and receive EUR.
But guess what, there are actually crypto solutions that can do that faster and cheaper than any bank can today. The trick is to go over crypto to bridge different fiat currency so you can exchange USD to EUR without a third party taking a fee for the exchange.
