this spreadsheet which shows every single 'dormant' bitcoin address with a balance of 25 bitcoins or more.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.The criteria for this spreadsheet was all bitcoins which haven't been touched since the price of bitcoin was less than $10 apiece; so around January 31, 2013.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 missed you.https://docs.google.com/spreadsheets/d/1xTROekDerP1TPOB3SOD_1bbQr580BPqbhF3YHdO96pw/edit?usp=sharingSome of the key addresses with the largest dormant balances are:With 79,957 bitcoins ($21 million dollars) here is the top one:https://blockchain.info/address/1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uFHere is #2, with 28,150 bitcoins without a single ever spend transaction since its creation on April 5, 2010. Nearly four years!https://blockchain.info/address/12tkqA9xSoowkzoERHMWNKsTey55YEBqkvWith 31,000 bitcoins untouched since May 13, 201, here is the address:https://blockchain.info/address/12ib7dApVFvg82TXKycWBNpN8kFyiAN1drThat's a whole lot of 'stored bitcoin' energy waiting to come out and play at some point in the future...Feel free to use this spreadsheet for research and post any interesting observations you might find.
