BTC: 30-Day Creation Window — Realized Price — Known Basis

Bitcoin 30-Day Creation Window — Realized Price — Known Basis was $79,888.4 on 7 Nov 2026 (latest daily value).

The average purchase price of the bitcoin bought in the last 30 days and still unmoved, in US dollars.

Why use it. It is the newest buyers' break-even: price above it means recent buyers are in profit, below it that they are at a loss. How to read it. Price below this line means last month's buyers are under water, a common sign of capitulation risk; price above it means they are in profit. Change returning to senders and miners' new coins are included while unmoved.

Calculation. How ours differs: a coin's purchase price is the BTC price on the day its unspent output was created, and coins without a known price are left out. Exact definition: The known creation-price average of still-unspent spendable outputs created in the latest 30 UTC calendar days of each daily snapshot. Higher values mean recent outputs were created at higher admitted prices. This is the price basis of outputs, not owners' purchase cost. Unknown-price supply is excluded and reported separately; a zero known denominator gives no value. Change, self-transfers and coinbase outputs are included while still unspent. Daily raw values only. Median-time-past closure and six-block depth determine finality, and price revisions remain material even for closed rows. For reporting day D, select spendable unspent outputs whose header creation date is from D - 29 through D, sampled after the highest canonical block assigned to D. Divide the sum of each selected output's satoshis × its admitted creation-day BTC/USD price by the selected known-price satoshis. Creation day C uses the price at C 00:00 UTC: admitted daily closing quotes from 2010-07-18, later admitted prospective quotes within 15 minutes, with no carry. Genesis, provably unspendable outputs and BIP30 retirements are excluded. 40-significant-digit presentation.
