STH Realized Price
The average price paid by recent buyers — people whose coins last moved within the past 180 days. Above the line they are in profit; below it they are underwater.
The average price at which coins that changed hands in the last 180 days last moved. It is the cost base of the market's newest and most nervous money.
Bitcoin trading **above** the line means recent buyers are in profit and less likely to sell in a panic; **below** it they are underwater, which historically has added selling. For example, a price of $95,000 against a line at $103,000 means the average recent buyer is about 8% down.
In words: the total paid for coins younger than 180 days, divided by how many of those coins there are. Our Bitcoin indexer computes both parts from the live UTXO set at every UTC-day close.
Every point on screen was counted by **our own Bitcoin node** — a full copy of the blockchain that we run ourselves. Until early 2011 part of this group still dated from before Bitcoin had a market price and counts at a cost of zero, so the first months sit far below the price. A day our node could not count is left as a gap; it is never filled in from another source.
Safu uses a transparent 180-day boundary so this chart agrees with the six-month edge in our HODL and LTH/STH supply charts. It is not Glassnode's proprietary 155-day definition. Cost basis uses each output's creation-day close, not an intraday execution price. Note on the age split: our node's history before 2026-08-17 was replayed with a 155-day split between short- and long-term holders; from 2026-08-17 it uses 180 days, so the line can shift slightly on that date.
Safu's own Bitcoin node, recomputed daily from the chain. Our node's rows run back to 2009; the line starts on 18 August 2010, Bitcoin's first day with a market price, because before that every coin's cost was zero. No outside data is used.
