NVT ratio
Also known as Network value to transactions.
- Definition
- The NVT ratio divides bitcoin's network value by the value settled on chain each day, borrowing the logic of a price-to-earnings ratio for a network with no earnings.
Willy Woo popularized the measure in 2017, when almost all bitcoin activity still touched the base chain. That assumption has broken: exchange internal ledgers, Lightning payments, and spot ETF shares changing hands all move bitcoin exposure without touching the chain. A high reading today can mean the price is stretched, or that settlement has moved somewhere the metric cannot see.
How it works
The NVT numerator is market capitalization and the denominator is the dollar value of transactions confirmed in a day, usually smoothed over a moving average because raw daily volume is far too noisy.
Work an example. A 2 trillion dollar network settling 10 billion dollars a day scores 200. The same network settling 40 billion a day scores 50. In the years Woo studied, readings mostly lived between about 20 and 90, and anything sustained above that band was read as the price running ahead of usage. The widely used NVT signal variant divides by a 90 day average of transaction value, which trades responsiveness for a chart that is actually readable.
The denominator needs more cleaning than people expect. A raw sum of transaction outputs double counts change: send 0.1 bitcoin from a 1 bitcoin output and the chain records roughly 1 bitcoin of output value, most of it returning to you. Providers that publish an adjusted transfer value strip that out, along with obvious self-spends, and the adjusted and unadjusted series can differ by a large multiple. A single exchange rotating 10,000 coins between its own cold wallets can distort a day's reading on either version.
Where you see it
NVT appears in valuation research and in arguments about whether bitcoin's price is supported by real usage.
The problem is that the denominator now measures a shrinking slice of what bitcoin does. Exchanges match trades on internal databases and only touch the chain on deposit and withdrawal, and they batch those: a single confirmed transaction can carry hundreds of customer payouts. Lightning moves payments through channels that settle on chain only when opened or closed, and the public channel capacity alone has been in the thousands of coins for years. Spot ETFs let institutions trade bitcoin exposure entirely inside a stock exchange while the underlying coins sit still at a custodian.
Every one of those developments pushes economic activity out of the denominator while leaving the numerator untouched, which mechanically raises the ratio over time. A reading that once signalled a bubble may now signal nothing but a maturing settlement stack.
For anyone buying bitcoin, the honest use is narrow. NVT is a research tool for comparing on-chain throughput with valuation, and reading it as a valuation verdict means treating a base layer that increasingly settles other layers as if it were still the whole economy. Nothing about your fees, your custody choice, or the legality of buying where you live shows up in it.
