It looked like an ordinary letter, delivered with all the rest of the mail to Daniel Levinson's San Francisco home. Thomas said since the New York Times profile, hundreds of people around the world have reached out to him with advice -- some serious and others silly. "One person suggested, have you tried the word 'password'?" he joked. "Some people have recommended various mediums, psychics, prophets that I could talk to. Some people are suggesting nootropic memory enhancing drugs." So far, he's not taken anyone up on it. Ian Sherr, Editor-at-Large at CNET News, explained that Thomas' situation is not that uncommon. "The way that Bitcoin works, and that this technology works, is that it's all meant to be anonymous," Sherr said. "But a lot of this data is actually hidden behind a specific password that you have to get into your account."
