    One day after $53 million abruptly disappeared from an experimental cryptocurrency project, a note appearing to be from the attacker has surfaced on PasteBin, claiming that the money drained from the system is now legally his. The attacker withdrew the money by exploiting a contract bug in the code of the DAO (or Decentralized Autonomous Organization), a collective investment fund that uses the Ethereum cryptocurrency. The DAO had raised well over $100 million from Ethereum users at the time of the attack.

    "I have carefully examined the code of The DAO and decided to participate after finding the feature where splitting is rewarded with additional ether," the note reads. "I have made use of this feature and have rightfully claimed 3,641,694 ether, and would like to thank the DAO for this reward."

      "The bitcoin price chart is showing us what we want to see: steady advance with reasonable corrective pauses. $700 has been strung up and left behind. Bitcoin price wears its new boots like a determined Sandor Clegane."

      From the analysis pages of xbt.social, earlier today:

      Bitcoin price has surged through $700 and touched $750 in the most popular USD exchanges. The OKCoin 3Month futures contract hit near $850 during early trade, and – soaring way above them all – the CNY exchanges are approaching a resistance zone near 5500 CNY (blue zone in the chart above). The equivalent USD level is around $900 (Bitstamp).
