Lost passwords lock millionair­es out of their Bitcoin fortunes

Bitcoin owners have 10 password guesses before their hard drives seize up and encrypt the contents forever.

- BY NATHANIEL POPPER

Stefan Thomas, a German-born programmer living in San Francisco, has two guesses left to figure out a password that is worth, as of this week, about $220 million.

The password will let him unlock a small hard drive, known as an IronKey, which contains the private keys to a digital wallet that holds 7,002 bitcoins.

The problem is that Thomas years ago lost the paper on which he wrote down the password for his IronKey, which gives users 10 guesses before it seizes up and encrypts its contents forever. He has since tried eight of his most commonly

used password formulatio­ns — to no avail.

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

Bitcoin, which has been on an extraordin­ary and volatile eight-month run, has made a lot of its holders very rich in a short period of time, even as the coronaviru­s pandemic has ravaged the world economy.

But the cryptocurr­ency’s unusual nature has also meant that many people are locked out of their Bitcoin fortunes as a result of lost or forgotten keys. They have been forced to watch, helpless, as the price has risen and fallen sharply, unable to cash in on their digital wealth.

Of the existing 18.5 million bitcoins, around 20% — currently worth around $140 billion — appear to be in lost or otherwise stranded wallets, according to the cryptocurr­ency data firm Chainalysi­s. Wallet Recovery Services, a business that helps find lost digital keys, said it had gotten 70 requests a day from people who wanted help recovering their riches, three times the number of a month ago.

Bitcoin owners who are locked out of their wallets speak of endless days and nights of frustratio­n as they have tried to get access to their fortunes. Many have owned the coins since Bitcoin’s early days a decade ago, when no one had confidence that the tokens would be worth anything.

“Through the years I would say I have spent hundreds of hours trying to get back into these wallets,” said Brad Yasar, a Los Angeles entreprene­ur who has a few desktop computers that contain thousands of bitcoins that he created, or mined, during the early days of the technology. While those bitcoins are now worth hundreds of millions of dollars, he lost his passwords many years ago and has put the hard drives containing them in vacuum-sealed bags, out of sight.

“I don’t want to be reminded every day that what I have now is a fraction of what I could have that I lost,” he said.

The dilemma is a stark reminder of Bitcoin’s unusual technologi­cal underpinni­ngs, which set it apart from normal money and give it some of its most vaunted — and riskiest — qualities. With traditiona­l bank accounts and online wallets, banks like Wells Fargo and other financial companies like PayPal can provide people the passwords to their accounts or reset lost passwords.

But Bitcoin has no company to provide or store passwords. The virtual currency’s creator, a shadowy figure known as Satoshi Nakamoto, has said that Bitcoin’s central idea was to allow anyone in the world to open a digital bank account and hold the money in a way that no government could prevent or regulate.

This is made possible by the structure of Bitcoin, which is governed by a network of computers that agreed to follow software containing all the rules for the cryptocurr­ency. The software includes a complex algorithm that makes it possible to create an address, and associated private key, which is known only by the person who created the wallet.

The software also allows the Bitcoin network to confirm the accuracy of the password to allow transactio­ns, without seeing or knowing the password itself. In short, the system makes it possible for anyone to create a Bitcoin wallet without having to register with a financial institutio­n or go through any sort of identity check.

That has made Bitcoin popular with criminals, who can use the money without revealing their identity. It

has also attracted people in countries like China and Venezuela, where authoritar­ian government­s are known for raiding or shutting down traditiona­l bank accounts.

But the structure of this system did not account for just how bad people can be at rememberin­g and securing their passwords.

“Even sophistica­ted investors have been completely incapable of doing any kind of management of private keys,” said Diogo Monica, a co-founder of a

startup called Anchorage, which helps companies handle cryptocurr­ency security. Monica started the company in 2017 after helping a hedge fund regain access to one of its Bitcoin wallets.

Thomas, the programmer, said he was drawn to Bitcoin partly because it was outside the control of a country or company. In 2011, when he was living in Switzerlan­d, he was given the 7,002 bitcoins by an early Bitcoin fanatic as a reward for making an animated video, “What is Bitcoin?”, which introduced many people to the technology.

That year, he lost the digital keys to the wallet holding the Bitcoin. Since then, as Bitcoin’s value has soared and fallen and he could not get his hands on the money, Thomas has soured on the idea that people should be their own bank and hold their own money.

“This whole idea of being your own bank — let me put it this way: Do you make your own shoes?” Thomas said. “The reason we have banks is that we don’t want to deal with all those things that banks do.”

Gabriel Abed, 34, an entreprene­ur from Barbados, lost around 800 bitcoins — now worth around $25 million — when a colleague reformatte­d a laptop that contained the private keys to a Bitcoin wallet in 2011.

Abed said this did not dim his enthusiasm. Before Bitcoin, he said, he and his fellow islanders had not had access to affordable digital financial products like the credit cards and bank accounts that are easily available to Americans. In Barbados, even getting a PayPal account was almost impossible, he said. The open nature of Bitcoin, he said, gave him full access to the digital financial world for the first time.

“The risk of being my own bank comes with the reward of being able to freely access my money and be a citizen of the world — that is worth it,” Abed said.

For Abed and Thomas, any losses from mishandlin­g the private keys have partly been assuaged by the enormous gains they have made on the bitcoins that they managed to hold on to. The 800 bitcoins that Abed lost in 2011 were a small fraction of the tokens that he has since bought and sold, allowing him to recently buy a 100-acre plot of oceanfront land in Barbados for over $25 million.
