In an echo of what sometimes pleasingly happens in the physical world, Mt. Gox has found 200,000 missing Bitcoins worth around $116M in an old virtual wallet from 2011.
The exchange had shifted the money into the wallets, which were offline, in order to protect them from hackers.
However, 650,000 Bitcoins that were probably online and more prone to attack are still missing following a massive breach that caused Mt. Gox to file for bankruptcy.
