Net Capital Flow estimates how many US dollars are entering (positive) or leaving (negative) Bitcoin, measured on-chain.

It is the sum of two flows: the NRPL (Net Realized Profit/Loss), i.e. the profit or loss realized by existing holders when their coins move, which is the change in Realized Cap caused by coins that were already in circulation; and the issuance, the dollars needed to absorb the newly mined bitcoin (block subsidy × block price, fees excluded because they are already part of NRPL).

Net Capital Flow = NRPL + Issuance (USD). It is the theoretical daily change of the Realized Cap, computed from clean flows instead of differencing Realized Cap snapshots, which are noisy from one day to the next.

- 1D: daily flow (hidden by default, enable it from the legend).
- 7D / 30D / 90D: rolling calendar sums of the daily flow (90D hidden by default, enable it from the legend). The 30D area is green when capital is flowing in and red when it is flowing out.

How to read it
- Sustained positive 30D/90D flows accompany bull phases: new capital is paying higher prices than the coins' cost basis.
- Negative flows mean coins are being sold below their cost basis faster than new money arrives: capital is leaving the network, typical of corrections and bear markets.
- Crosses of the 30D and 90D flows through zero mark changes in the capital regime.
