Looks like a false alarm. Other blockchain explorer sites/tools don't show this transaction:<p>Biteasy: <a href="https://www.biteasy.com/blockchain/addresses/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX" rel="nofollow">https://www.biteasy.com/blockchain/addresses/12c6DSiU4Rq3P4Z...</a><p>Blockr: <a href="https://btc.blockr.io/address/info/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX" rel="nofollow">https://btc.blockr.io/address/info/12c6DSiU4Rq3P4ZxziKxzrL5L...</a><p>Blocktrail: <a href="https://www.blocktrail.com/BTC/address/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX" rel="nofollow">https://www.blocktrail.com/BTC/address/12c6DSiU4Rq3P4ZxziKxz...</a><p>WalletExplorer: <a href="https://www.walletexplorer.com/wallet/1cd472673f5a7d4f?from_address=12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX" rel="nofollow">https://www.walletexplorer.com/wallet/1cd472673f5a7d4f?from_...</a>
For those not aware, the original 50 coins sent to this address were generated from the genesis block, the first block on the blockchain. However, the transaction is still unconfirmed, so until it is this could be nothing. Market has been scared downwards though.
It only appears to be recorded on blockchain.info. None of the other blockchain explorers seem to see it.<p>I'd hold off on the news until it's been confirmed.<p>Edit: Others have checked and can't find any of these transactions in the blockchain. Either a blockchain.info bug or hack at this point. Nothing has moved.

At an exchange rate of $284.45 USD/BTC, this comes out to a transaction of a little more than $14,000. However, as creator of the Bitcoin protocol and an early adopter, and that this is one of his oldest wallets, he may be moving unknown quantities of Bitcoin. This could cause a disruption on the open BTC markets if he exchanges a large quantity -- but for what reason? No one knows, since Mr. or Ms. Nakamoto is anonymous.
