Bitcoin Net Unrealized Profit/Loss#
Definition#
Bitcoin Net Unrealized Profit/Loss measures the gap between market cap and realized cap as a share of market cap.
In CoreCharts, market cap is daily supply multiplied by daily BTC price in USD. Realized cap is the aggregate USD cost basis of current supply, built from the price at which coins last moved.
The unit is a ratio. Positive values place market cap above realized cap. Negative values place it below.
This is not a price momentum indicator, not a flow measure, and not a realized P/L series. It is a valuation spread built from current market value and on-chain cost basis.
Interpretation#
High positive readings appear when a large share of network value sits in unrealized profit. That usually happens late in strong bull phases, after price has moved well above aggregate cost basis and stayed there long enough for the supply to reprice unevenly.
Values near zero put market cap close to realized cap. Embedded profit across the network is limited in that state. These zones tend to appear around broad repricing phases, when spot valuation sits near the average on-chain acquisition base.
Negative NUPL places market cap below realized cap. Aggregate unrealized loss then outweighs aggregate unrealized profit. Those periods have historically lined up with deep drawdowns, forced repricing, and holder stress.
Price And Market Regime#
Profit-Heavy Regimes#
A rising NUPL widens the upside gap between market cap and realized cap. Price is advancing faster than coins are being repriced on-chain, so unrealized gains accumulate across dormant supply.
Very high readings usually require two conditions at once: a strong price advance and a realized cap base that has not caught up. Freshly repriced supply can slow that process. Older low-cost supply can magnify it.
Repricing Zones#
A falling NUPL narrows the gap between market cap and realized cap. Sometimes price is dropping. In other cases, realized cap is rising into a stable market because coins are changing hands at higher prices and lifting aggregate cost basis.
The same NUPL decline can therefore describe a bearish markdown or a post-rally ownership reset.
Loss-Dominant Regimes#
Below-zero readings place market cap under realized cap. The network is then carrying aggregate unrealized loss.
Those periods are rare in Bitcoin’s history and usually cluster around capitulation phases. They do not identify the exact timing of a bottom. They define the valuation state of the outstanding supply.
Relationship to other metrics#
Realized Cap is the base beneath NUPL. Realized cap moves when coins move and inherit a new on-chain cost basis.
MVRV Ratio uses the same two components in a different form. MVRV is Market Cap / Realized Cap. NUPL expresses the same valuation gap as a share of market cap, so the two series often move in the same direction with different scaling.
MVRV Delta keeps that spread in absolute USD terms: Market Cap - Realized Cap. NUPL normalizes the spread by market cap, which makes the output dimensionless and more stable across eras with very different nominal capitalization.
Net Realized Profit/Loss sits on the realized side of the ledger. It records P/L when coins move. NUPL stays on the unrealized side and tracks the mark-to-market condition of current supply.
Historical Background#
NUPL was introduced in Bitcoin market analysis by Tuur Demeester, Tamás Blummer, and Michiel Lescrauwaet in Adamant Capital’s 2019 work on investor sentiment and saving behavior. The metric took the realized cap framework and turned the gap between market cap and realized cap into a normalized ratio.
Realized cap came earlier. It was developed at Coin Metrics in 2018 and became the accounting layer from which later valuation metrics such as MVRV and NUPL were derived.
