The Mars economy will run on bitcoin, dogecoin or marscoin according to Elon Musk, the CEO of SpaceX. Responding with a yes to the statement the Mars economy will run on crypto, Elon Musk has now made it official that bitcoin is the space currency. According to some analysis, transacting in bitcoin with Mars pioneers would take 6.5 minutes. As bitcoin’s block-times are ten minutes, the distance should not be a problem, especially if they use something like the Lightning Network.
