TechFlow reported that during an X Spaces session with ARK Invest CEO Cathie Wood, Musk initially rejected using Bitcoin as Mars' currency due to the long transaction settlement times. After brainstorming on his own, Musk concluded it might actually be feasible—given Earth is only 8 light-minutes from the Sun while Mars is about 12 light-minutes away—though it would still face obstacles.
Musk has long been committed to establishing a colony on Mars by 2050, believing humanity must evolve into a multi-planetary species to survive.
