I find this article interesting but there are things needed to consider before implementing this kind of idea. Hell, everyone is still debating if the external and internal conditions on Mars is habitable or if life can exist there and people are already talking about the currency to use there!
Going back to the question, introducing cryptocurrency as its foundation would always start at Earth- meaning all transactions will be utilized in our planet first before implementing it to Mars. That is why I highly doubt that it will materialize anytime soon.
I do like the article! I think its a whole point of developing into a new society no borders,including currency.
Besides, using fiat on another planet is a nonsense. There will be different hierarchy and different needs, a brand new history.
Moreover only psychologically stable people will make it to Mars. So its very likely they wont need that game attributes we use here on Earth.
It would be actually interesting if it were to be implemented but I highly doubt so. People are already thinking of the currency to be used on Mars but everyone still doubts if life can exist there! I find the irony indeed funny!
