NUPL is a specific Trading coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: Net Unrealized Profit/Loss estimates aggregate paper profit or loss relative to realized capitalization. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
NUPL is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
NUPL describes how participants value, trade or obtain exposure to bitcoin. Market behavior can affect adoption and mining economics, but it does not rewrite consensus rules. Price evidence and protocol evidence answer different questions.
Understanding NUPL helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: NUPL estimates aggregate unrealized profit or loss by comparing market capitalization with realized capitalization and scaling the difference by market capitalization under a provider's on-chain methodology. They should be verified before using the coordinate in analysis.
The practical limit is: it is not actual taxable profit, cash flow or every holder's cost basis; lost coins, exchange transfers, entity adjustment and price sampling affect the series, while named zones are retrospective heuristics. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
