The possibility of creating his own cryptocurrency, "Marscoin" was discussed by Elon Musk. The coin would allegedly be used to buy large amounts of Dogecoin and drive up its value. Discussions on the subject tend, however, to be mainly in jest. Musk has hinted that a cryptocurrency could be developed, although the possibility remains uncertain. Today's suggested idea has nothing to do with Mars; it relates to a potential purchase of Do Geocards.
