The best evidence for that is a process we set up to register for our launch event on May 11th in New York City. No credit cards or cash are accepted to buy a ticket. It’s crypto-only. What kind? It’s your choice. For eth fans with MetaMask, registering can be accomplished in literally 20 seconds.
Name -> email -> Metamask confirmed -> Click -> done.
