Stefan Thomas, of San Francisco, says he has made peace with forgetting his Bitcoin password that would turn him into a multimillionaire. Thomas, who recently was featured in The New York Times, has about $220 million worth of Bitcoin locked away on a hard drive that will erase its data after 10 password attempts.

Thomas has tried to put in the correct password eight times with no luck. The German-born programmer lost the piece of paper containing the password. “You sort of question your own self-worth. What kind of person loses something this important?” Thomas said during a recent interview with ABC7 News before detailing how he has come to terms with what happened. “It was actually a really big milestone in my life where, like, I sort of realized how I was going to define my self-worth going forward. It wasn’t going to be about how much money I have in my bank account,” he said.

Thomas said he told his story to help prevent others from forgetting their passwords.
