Go ahead and add the Winklevoss Twins to the growing list of notables locked in for a trip to aboard Richard Branson's Virgin Galactic.

Tyler and Cameron, famous for their dispute with Mark Zuckerberg over the creation of Facebook, have announced they're paying the $250,000 ticket price with the digital currency bitcoin.

In a blog post, Tyler adds: "Cameron and I have decided to use our bitcoin to take the plunge, or rather propulsion, into space. Why? Because Bitcoin and Sir Richard Branson’s Virgin Galactic are two technologies that meaningfully represent our focus at Winklevoss Capital - the reduction of pain-points and friction in an effort to build a better world."

The 34-year-old then explains in greater detail why Virgin Galactic and bitcoin are both major players in breaking down old barriers - a nice marketing move reflective of twins' huge investment in the digital currency.

"It is in this vein that Cameron and I contemplate our tickets into space – as seed capital supporting a new technology that may forever change the way we travel, purchased with a new technology that may forever change the way we transact," he writes.

In a recent interview, Richard Branson reiterated his belief that the first six-person flight aboard Virgin Galactic will happen later this year. NBC announced last November that it will air an exclusive live special of the flight - with Branson and his children Sam and Holly scheduled to be on board.

"Without a doubt, Sir Richard and his children taking the first commercial flight into space, will go down in history as one of the most memorable events on television," Sharon Scott, president and general manager of Peacock Productions, said in a statement.
