Bitcoin—the world's best boost to a brand?

The debate may continue to rage over whether bitcoin is a viable alternative to the dollar or just another Ponzi scheme, but there's no denying of its ability to boost a brand's awareness.
Billionaire entrepreneur Sir Richard Branson announced on CNBC's "Squawk Box" Friday that his commercial space flight venture will accept bitcoin as payment. His tweet confirming the move received nearly 500 retweets and the corresponding story on CNBC received over 4,000 Facebook shares and was one of the most read articles on the site that day.
