If space travel and virtual currency don’t take off, it won’t be because the Winklevoss twins didn’t try. The brothers, known for their legal battle over the creation of Facebook are going to space and paying for it with Bitcoins. Take that, Mark Zuckerberg. The twins bought tickets, valued at $250,000 each, for a ride to space with Virgin Galactic. That’s about 375 Bitcoins, at Wednesday’s price. They think of their purchase “as seed capital” supporting new technologies they have high hopes for.
