The finance industry and others are moving to a blockchain, it has not yet been adopted in full or implemented.
my personal suspicion is that the finance industry will never find a use for a public blockchain.
i've heard of people who've attended some of these professional conferences coming back with the impression that very few of the attendees knew anything about it and were there to look cool. but that's ok because real people will force them to deal with it whether they like it or not.
I work on finance industry, with IT at a Multinational Bank, directly with CEOs. I can confirm most people working on research and attending weekly conferences within banking corporation CEOs know NOTHING - I repat:
NOTHING about crypto and some top analysts don't even have had contact with Bitcoin or any other coin whatsoever. Such a shame.
