BTC: Realized Price by Creation Year
Shown as its 2019–2022 sample; the latest readings and full history are included with Plus.
The average price paid for the bitcoin created in each calendar year that has not moved since: one line per year, the realized price of that year's unspent coins.
Why use it. Each line is the break-even price of a vintage of holders, such as everyone whose coins last moved in 2024. When the price falls through a recent year's line, that year's buyers move from profit to loss on average, a level many watch as support or resistance. How to read it. A line above the price means that year's remaining coins are at a loss on average, below it in profit. A year's line drifts as its coins are spent: when holders who bought high sell, the remaining coins' average falls, and the reverse. The current year's line moves most, as new coins join it every day.
Calculation. For each day and creation year Y: the sum of each unspent coin created in Y × the BTC/USD price at the start of its creation day, divided by those coins. A coin's year is the UTC year of the day its output was created, so a coin that moves joins the year it moved in. Coins created before 18 July 2010 have no cost basis and are left out. Computed by CryptoKeyhole from its own validated Bitcoin Core node's record of every unspent output by the UTC day it was created, valued at the BTC/USD price at the start of that day (coins created before 18 July 2010 have no cost basis and are left out). BTC/USD prices are the site's admitted daily closes (The Bitcoin Time Machine, CC BY 4.0, until 2 October 2026, then quotes recorded from Alternative.me). Values for closed days are provisional, like their inputs; the open day is a partial at the latest completed hour, recomputed every ten minutes.
