Stefan Thomas, a German programmer living in San Francisco, owns 7,002 bitcoins in a digital wallet, which are worth $220 million. But the programmer can't access the money because he lost his password. He has tried eight times to guess the code, but with no success. Now, Thomas has just two more chances to guess his password correctly before the money is lost. The hard drive, known as IronKey, where Thomas' bitcoins are held allows users 10 attempts to correctly guess their password before encrypting the contents permanently. Bitcoin also can't help Thomas, since it doesn't store its users' passwords. Instead, it gives users their own private IronKey, which only they have access to. Posted By Persist
