While the price of bitcoin has skyrocketed significantly in history by 92% increase in just one month and about 340% in a year, one German-born investor and programmer who dwells in The United States of America, San Francisco, by the name of Stefan Thomas is locked out of accessing his riches because he forgot his password.

Speaking to The New York Times this week, the programmer said that he had two tries left to guess his password to a hard drive that holds the keys to his wallet with $220 million worth of bitcoins (7,002 bitcoins)

“I would just lay in bed and think about it,” Thomas told The Times’ Nathaniel Popper. “Then I would go to the computer with some new strategy, and it wouldn’t work, and I would be desperate again.”

IronKey is a secured hard drive that gives users 10 guesses to get their password right before encrypting the hard drive’s contents; Thomas has two more chances left.

As some investors of bitcoin become multi-millionaires in dollars, others already have problems gaining entry into their own investments because they’ve forgotten the passwords to their IronKeys.
