As the digital currency bitcoin has skyrocketed lost private key bitcoin value, many of the early adopters have become millionaires lost private key bitcoin only if, that is, lost private key bitcoin can find their bitcoins.

Kenny Malone from our Planet Money team went on a virtual treasure hunt. Syl Turner heard about bitcoin about 10 years ago, lost private key bitcoin he figured, what the heck, got a couple of coins and then saved them to what's known as a digital wallet on his hard drive.

You know, at the time I didn't think bitcoin was worth anything so I didn't laughterback anything up. To be fair, it wasn't worth anything at the time. Turner had digital pennies and then let them fall between the digital couch cushions. And so Turner is lost private key bitcoin in his attic, staring at a waist-high layer of junk, looking for a year-old hard drive. Jonathan Levin is co-founder of Chainalysis, a company that makes bitcoin analysis software, and the company did a study that found around 20 percent of all bitcoin is lost, out of circulation.

And Levin says lost private key bitcoin confusing thing is that, technically speaking, bitcoin can't be lost. Blockchain - big word, sure, but here's a very non-technical way of understanding what it means. Imagine with me, if you will, a massive auditorium lost private key bitcoin with bitcoin bookkeepers. Now, Jonathan wants to send me one bitcoin. He walks on stage in front of all these bookkeepers, steps up to a microphone, and he's like Hello, entire bitcoin universe.

As all of your books show, I, Jonathan, have three bitcoins to my name. After Jonathan says this, all of these virtual ledger keepers sort of scribble this lost private key bitcoin down, deduct one bitcoin from Jonathan's account, increase Kenny's account by one, and that is a bitcoin transaction. Nothing is really transferred. It's more like an instantaneous adjustment across a whole bunch of ledgers. When people talk about the blockchain, they're talking about this system where there is no central bookkeeper.

Whatever bitcoins Syl Turner has, they're still there sitting in a kind of virtual vault, but he has lost the key. He's looking for an old hard drive with a super complicated password, and it's not up here. Bitcoin was created to be this decentralized currency. There's no federal reserve tweaking interest rates, there's no treasury department printing new money and there's no customer service line to call if you are Syl Turner.

But that lost bitcoin expert Jonathan Levin, he does have a phone number. So we have gathered here today to try and resurrect Syl's lost bitcoin. Turner explained how he knows he's got tens of thousands of dollars of bitcoins locked away, he just cannot find that hard drive with the digital wallet lost private key bitcoin the private key. Well, what we need to find the needle in the haystack is even, like, a little bit of a key. What Levin is saying is that bitcoin private keys are designed to be un-guessable even by the most powerful computers we have right now.

But if Turner happened to write down part of this key at some point, there are companies that will use that information to help him break into his account. But, like lots and lots of other early bitcoin enthusiasts, Syl Turner did not write down any part of the key and has nothing to go on. I know this is going to be, like, my deathbed regret.
