“Bitcoin is now officially mainstream. According to BTC Geek (archived link), Bloomberg terminal users can now look up Bitcoin’s pricing history. Data comes from ubiquitous Bitcoin exchange service Mt. Gox as well as Tradehill (Archived link for https://tradehill.com/). For now, only Bloomberg employees can access the ticker. But the feature should make its way to regular Bloomberg terminal customers under the label XBT. The ticker probably shows what a bitcoin is worth in U.S. dollars over time. With the Bloomberg terminal, traders could easily compare Bitcoins with other currencies in order to short them.”
