What industries / specific companies are you looking forward to crypto killing off?

Everybody in this sub who isn't a troll assumes that crypto it's going to replace a number of different Industries, most obviously banking and especially money transfer companies. I was surprised to see the vehement excitement with which people in here greeted the assumed imminent death of Ticketmaster and its competitors at the hand of blockchain tech, but hurray for that!

What other Industries or specific companies do you think crypto is going to kill off? Are there any that you're so confident it will destroy that you are shorting them? Are there any companies you just hope it will kill off because you hate them so much?

Edit: is there any type of crime that blockchain makes impossible?
