All the Y Combinator companies combined have created value.

What has Bitcoin created?

I struggle to come up with an answer which isn't overwhelmingly just a way to fund illicit activities, for which sure there's always been a market, but it's a far cry of it's origins. Who actually uses bitcoin for transactions today other than extortionists hackers and drug dealers? Everyone who owns is just planning to HODL and hope that it will become equivalent to an infinitely high fiat equivalent. Had bitcoin succeeded we wouldn't be talking about insane valuations. We would be using it every day no different from a credit card.
