TOKYO — A major bitcoin exchange has gone bust after secretly racking up catastrophic losses, other virtual currency companies said today — a potentially fatal blow for the exotic new form of money.
The website of Tokyo-based Mt. Gox was returning a blank page today. The disappearance of the site follows the resignation Sunday of Mt. Gox CEO Mark Karpeles from the board of the Bitcoin Foundation, a group seeking legitimacy for the currency, and a withdrawal ban imposed at the exchange earlier this month.
