I'm not saying crypto or distributed ledger technologies are a fad. I'm saying that the bitcoin blockchain implementation and especially the idea of a stand-alone currency that is needed in the system is probably a fad.
A fad on the WSJ front page still getting tens of millions of dollars of VC funding this month alone, after 6 years?!
If it is a fad why are you here on a Sunday?
Have you actually read the WSJ article? Very superficial understanding about bitcoin and the blockchain.
Plenty of hype articles during 2014 right before crashes too.
