Prices on the main exchange, Mt. Trading was suspended and eventually rolled back to pre-crash rates. Gox revealed details of the security breach on June 20 with an announcement on its website. This allowed for someone to pull our database," the statement read. Around the same time, an unidentified person accessed one of the compromised accounts and sold all of its Bitcoins.

On the same day as the crash, the EFF's legal director Cindy Cohn wrote : "Since there is no caselaw on this topic, and the legal implications are still very unclear, we worry that our acceptance of Bitcoins may move us into the possible subject role.

Bitcoin developer Gavin Andresen conceded that current safeguards around the currency may be inadequate. Virtual sales aid poorer nations. China cracks down on virtual cash.
