Revenge of the Winklevii?
I admit, when I heard about their involvement in this bitcoin madness awhile back, I saw it as a desperate hail-mary attempt to strike it big in tech like they narrowly missed before. They did not actually build anything here, but their bet seems to be pretty sound so far with the price rises.
I've been combing the net for more details and implications, and this video seemed interesting.
It's a bit bizarre to hear it, but this kind of stuff taking off is the same concept of galactic "credits" from star wars or firefly.
And different versions have different properties, even some potentially "untraceable" credits like Jayne was so pissed off at losing upon hearing the ballad of Jayne.
