It has decided to roll back a days’ trading as a result of the stolen bitcoins, which were dumped on the market, crashing the value of a single bitcoin. Apparently there wasn’t that much cash involved (only $1000,-) which means that the bitcoin currency isn’t very strong at all.

Concurrently, a trojan has been found that scours your hd for bitcoins, and on top of that a hacker has released accounts and passwords for a slew of bitcoin users.
