BTC: UTXOs Aged <155 Days — Unrealized Loss — Priced Supply

Bitcoin Short-Term Holder Unrealized Loss was $13,164,901,927.79 on 7 Nov 2026 (latest daily value).

The total paper loss of Bitcoin's short-term holders, in dollars: for every coin that moved within the last 155 days and worth less now than when it last moved, the loss, added up.

Why use it. It shows how much pain this group is sitting on; large losses have come near capitulation. How to read it. It only adds losses, shown as a positive amount; gains are in the unrealized profit chart. It is loss on paper, not money lost.

Calculation. How ours differs: the holder groups are set by coin age, not by owner: short-term means coins that moved within the last 155 days, long-term coins unmoved for 155 days or more, counted from each coin's last move (the block time of its unspent output), with no adjustment for who owns them. Only coins whose purchase day we can price are counted; coins without a known price are left out, not valued at zero, so read unknown-price BTC and price coverage alongside it. Exact definition: Positive unrealized loss magnitude on known-basis unspent value for spendable outputs under 155 fixed days old. The loss magnitude is positive, not a signed negative balance or an executed loss. Zero is valid with positive priced BTC; absent market quote or no positive priced BTC is undefined. Use exact creation-header age at that snapshot: older means creation time at or before its header time minus 155×86,400 seconds; later or future-dated creations are younger. Header regressions are retained; request time does not age the stock. Read unknown-price BTC and price coverage alongside the result. Unobserved history stays unknown; genuine source/price holds and partial/provisional/final labels remain in force. For each known-basis BTC amount, sum only positive creation-basis minus period-end-price differences times that amount. The spendable snapshot follows the highest canonical block assigned to the UTC period, including eligible coinbase/change but excluding genesis, provably unspendable outputs and BIP30 overwrite losses. Use local canonical Bitcoin outputs and undo facts with separately admitted creation-day-start BTC/USD quotes. Historical daily boundaries use retrospective previous-day closes with unknown release time and vintage; hourly quotes use recorded prospective observations. Method retains provider credits and price rights. Missing prices are never filled.
