Lost bitcoin wallets list. 20% of All BTC is Lost, Unrecoverable, Study Shows
These are not what I have been previously referring to as 'zombie' bitcoins, for which I have been using a 3 year age cutoff value. This cut-off was a bit arbitrary, and feel free to sort the spreadhsheet and use different cutoff values yourself. However, knowing that these coins must have a cost basis just a fraction of the current value of bitcoin over the past two years, we can now consider how many are out there waiting to re-enter the market. This list includes the approximately one million mined bitcoins for the first year or so of the lifetime of the blockchain, presumably owned by Satoshi and untouched to this date.
Others probably represent wallets which have been lost forever. And, of course, many just represent steely eyed holders who quietly fondle their private keys dreaming a future world economy running on bitcoins.
Here is a link to a Google Docs spreadsheet containing all of the addresses. If you have an old dormant address with more than 25btc, go ahead and check it against this spreadsheet and let me know if I vine with options lost bitcoin wallets list.
