Oh dear! What a bummer … just imagine what you would be doing right now!
Taken from BBC … programmer Stefan Thomas has forgotten password that will let him unlock a hard drive containing $240m (£175m) worth of Bitcoin. His plight, reported in the New York Times, has gone viral.
Ex-Facebook security head Alex Stamos has offered to help – for a 10% cut.
Bitcoin has surged in value in recent months. One bitcoin is currently worth $34,000. But the cryptocurrency is volatile. And experts are divided about whether it will continue to rise or crash.
Mr Thomas, who was born in Germany but lives in San Francisco, was given 7,002 bitcoins as payment for making a video explaining how cryptocurrency works more than a decade ago. At the time, they were worth a few dollars each.
He stored them in an IronKey digital wallet on a hard drive. And he wrote the password on a piece of paper he has lost.
After 10 failed attempts, the password will encrypt itself, making the wallet impossible to access.
