Cryptocurrency Wallets - Lost Key Shockers

Cryptocurrency Wallets - Lost Key Shockers
Holding cryptocurrency is known to carry risks. Here we share five scary stories where the owners have lost access to their funds and in all but one case lost their cryptocurrency forever.

The big one - $1Bn inaccessible

On April 16, 2018, Matthew Mellon of the Mellon banking fortune died. As the sole proprietor and protector of his Ripple coin private keys, inevitably these went to his grave with him.

At the time of his death, he held an estimated one billion dollars in Ripple. Without those private keys, these remain locked up on the blockchain forever. 


The unfortunate one - Priceless rubbish

In 2013, James Howells from the UK had mined 7,500 bitcoins, which he stored on a laptop hard drive. When the computer stopped working, he mistakenly threw away the hard drive during a spring clean. The keys, along with all his other waste, ended up at a local dump.

In 2017 at the peak of Bitcoin value, his buried treasure would have been worth around $150,000,000.


The one and the many - $135m taken to the grave

In December 2018, Gerald Cotton, CEO of QuadrigaCX, Canada's largest cryptocurrency exchange, died unexpectedly. Unfortunately for QuadrigaCX's customers, Mr Cotton was the only person who was able to access the private customer keys.

As a result, over US$135M in customer funds held in safekeeping was deemed inaccessible, locked on the blockchain forever.


The accidental one - '$300m in cryptocurrency' accidentally lost forever due to bug

In November 2017, a cryptocurrency developer was working to improve the security of his clients' wallets. Unfortunately, the security update was too good! After mistakenly taking control of hundreds of wallets, he accidentally locked and deleted all of the private keys in his panic to put them back. 

With over $300m of client cryptocurrency lost by accident, it is no wonder the developer decided to remain anonymous. 



The lucky one - Tech journalist recovers $30,000 of Bitcoin after six-month ordeal.

In January 2016 a respected tech journalist decided that he needed a  hardware device to store his bitcoins. He was using a Trezor hardware wallet and it worked well up until the time he forgot his PIN! 

Turning to his backup notes, he soon realised these had been tossed out following a deep clean. With the PIN forgotten and the backup lost, he tried multiple times to guess the number. Each attempt, the time between guesses doubled, meaning it would take 34 years to make the 31st guess! 

Ready to write off the bitcoin, having even tried hypnosis to remember the pin, ironic salvation appeared months later in the form of a Trezor security hole. Using the security floor, and the assistance of a hacker, the Journalist, was able to recover his bitcoin after months of worry.
