Future of top U.S. Bitcoin exchange in doubt as $250K in virtual currency stolen

The future of the top U.S. Bitcoin echange is in doubt after $250,000 in virtual currency was stolen last night.
As CNet reports, an unidentified hacker found and absconded with an unencrypted backup of virtual wallet keys, taking 24,000 bitcoins, each worth just over ten U.S. dollars. It’s the virtual equivalent of leaving your wallet on the cafe table as you go to use the restroom.
