Thanks to Bob Greenyer for finding this.
Well-known American economist Paul Krugman posted this tweet on Twitter yesterday:
So the blockchain in interesting, but not yet clear whether it's useful for anything. And investing in Bitcoin still looks a lot less reasonable than investing in cold fusion 12/

My guess he is being ironic here, probably thinking that ‘junk science’ cold fusion may actually have more actual value than Bitcoin, which along with other cryptocurrencies he doesn’t seem to think very highly of. Or else Krugman has been paying attention, and may think there is something of value in CF/LENR.
I do have a hope that at some point we may see a similar amount of interest in the LENR field that we are seeing at the moment with cryptocurrency.
