"exciting" is subjective though.. Dont forget that the media and popular culture highly inflates the potential of a new technology and made promises about the moon and sky about it. Before the people hears the dissapointing news from the real scientists who invented the thing and what they did fades into obscurity and then they change the world. Know about the Gartner Hype Cycle? You should take a look...
But that is looking at a "business as usual" mindset popular in corporate culture. Notice that it says "Blockchain" instead of cryptocurrency? Because cryptocurrency scares the corporate. But I digress.
No one knows whats the "next best thing" and anyone who does are either trying to sell you something, make themselves famous, or is talking non-sense. Sometimes usually all three at the same time.
Literally no one predicted Bitcoin until it came out. And i'd say its the most world changing invention in our generation.
