I wonder about the end of the story. Will there be an infinite number cryptocurrencies? Will there be only one cryptocurrency which make all others superfluous? Somewhere in between the extremes? How improved or perfected can a cryptocurrency be? Is there something much better than blockchain that can do the same job much more efficiently?
How about an AI currency that efficiently rewards those that most deserve rewards? Code knows how those decisions might be made. What's going to happen your wonderland?
