What is Bitcoin NUPL?
Net Unrealized Profit/Loss (NUPL) is one of the most widely used on-chain sentiment indicators. It represents the difference between unrealized profit and unrealized loss across all Bitcoin in circulation, expressed as a fraction of market capitalization.
A NUPL of 0 means the market is exactly at break-even. Positive values indicate the aggregate market is in profit; negative values indicate the market is in loss — the capitulation zone that has historically marked major cycle bottoms.
NUPL zones explained
Capitulation (< 0)
When NUPL drops below zero, the majority of Bitcoin holders are sitting at a loss. Historically this has coincided with major market bottoms — 2015, 2018-2019, and March 2020. It is the highest-conviction buying signal the indicator produces.
Euphoria (> 0.75)
When NUPL exceeds 0.75, unrealized profits are extremely elevated relative to market cap. This zone has preceded all major cycle tops. Distribution by long-term holders tends to accelerate here.
How to use NUPL in Bitcoin analysis
NUPL works best as a cycle-context indicator rather than a standalone timing trigger. Readings below zero highlight periods when the market is underwater on aggregate, while very high readings show when unrealized profits have grown large enough to increase distribution risk.
Analysts usually compare NUPL with MVRV, realized price, SOPR, and long-term holder positioning. When multiple on-chain signals point in the same direction, the probability of a durable cycle signal improves.
