In the future, Bitcoin will become the primary currency for intergalactic space travel. With the rise of space tourism and the colonization of other planets, Bitcoin will be used as a universal currency across the galaxy. Miners will be sent on deep space missions to mine for new Bitcoin, and Bitcoin wallets will be implanted in astronauts' brains for easy access during long journeys. As humanity explores the vastness of space, Bitcoin will be the one constant that unites all civilizations.
