Bitcoin investors were left frustrated Thursday as a planned resumption of withdrawals from major exchange Mt Gox hit a hitch with the Tokyo-based company blaming a security breach for the delay.
Rather than a cyberattack, the security issue was in the real world, with Mt Gox saying it had to relocate to another part of the capital.
"In addition to the technical issue, this week we have experienced some security problems, and as a result we had to relocate Mt Gox to our previous ofﬁce building in Shibuya," it said.
"The move, combined with some other security and technical challenges, pushed back our progress...we are committed to solving this issue and will provide more information as soon as possible."
Mt Gox customers have been unable to withdraw their bitcoins and convert them into U.S. dollars since the beginning of February. The bitcoin exchange blamed the problem on a critical flaw in the cryptocurrency – known as "transaction malleability" -- which it said affected all exchanges.
On Monday, the exchange announced that users should soon be able to withdraw funds from their accounts amid growing tensions and a price collapse for the virtual currency. However, Thursday's update revealed that users still won't be able to able to transfer their investments.
