I like the concept of BitCoin but have been a bit cautious of it. This makes me even more so. But now might be the time to buy low.... .......................................................... Bitcoin prices plunged again Monday morning after Mt.Gox, the major exchange for the virtual currency, said technical problems require it to continue its ban on customer withdrawals. Mt.Gox said it has discovered a bug that causes problems when customers try to use their account to make a transfer or payment of bitcoins to a third party. It said the problem is not with Mt.Gox software but affects all transfers of bitcoins to third parties. The exchange said it was suspending withdrawals and third-party payments until the problem is fixed, although trading in bitcoins continues. A bug is allowing a third party receiving a bitcoin transfer to make it look as if the transfer did not go through, which can lead to improper multiple transfers, Mt.Gox said.

Prices had been as high as $831 just after 7 p.m. Thursday before Mt.Gox's halt of withdrawals was first disclosed early Friday morning. Bitcoin prices plunge as problems persist - Feb. 10, 2014 Added: http://dealbook.nytimes.com/2014/02/10/bitcoin-exchange-struggles/ From the creation of Bitcoin in 2009, one of the most important and vaunted features of the Bitcoin program was its ability to prevent the same coins from being moved to two different places at the same time. In its announcement on Monday, Mt. Gox said that a bug in the Bitcoin software made it possible for someone to use the Bitcoin network to alter transaction details to make it seem like a Bitcoin transfer had not occurred when, in fact, it had. The company said: “We have discussed this solution with the Bitcoin core developers and will allow Bitcoin withdrawals again once it has been approved and standardized.” Other exchanges did not report similar problems, but none of the biggest companies immediately put out a response. Beyond Mt. Gox, Bitcoin users have been rattled by several setbacks in recent days. On Friday, the Russian government said Bitcoin transactions were illegal. They joined the Chinese government, which said in December that financial institutions in the country could not participate in Bitcoin transactions. Florida prosecutors, meanwhile, arrested people on Friday who had met to exchange Bitcoins for dollars, the first such arrests. American authorities have generally given a tentative blessing to the Bitcoin experiment. But they have warned consumers about the dangers and the problems that could still pop up.
