I hope you can trade them while you are in space. I want fast transfer fees between Mars and the Sun! Since it's SpaceX Coins there should also be like the universe a limitless always expanding supply! Maybe some aliens will finally come see us and start to invest. If they now do exist then they probably got a hell lot more money than we do. They probably look at 1 trillion as tip money! Best part of all is there is truly no tax in space since it is very hard to regulate. Unless Elon sets up a Federal Reserve bank on Mars.
