In a perfect world where anything bad happens and out in the space we can make friendships with aliens, how big i the probability to use crypto technology for paying different alien goods. Or when the human species will be so developed that they will be able to colonise different planets and there will be an open market between planets, would they be able to trade with bitcoin or something similar?? I invite you for interesting points of view 
Why someone need money or should have trading concerns in space? Aliens will give you everything and whatever you ask.My brain gives error.. 
I couldn't help my self 
I have never been in space, unfortunately i'm afraid of hights but we should ask NASA what caind of financial need are out there in space, the final frontier. Finally a funny topic
