In February 2017, Willy Woo posted a chart on Twitter with a simple idea: what if you could value Bitcoin the way investors value a company’s stock?
For stocks, the price-to-earnings (PE) ratio divides a company’s market cap by its annual earnings. High PE means investors are paying a lot for each dollar of earnings — often a sign of overvaluation or high growth expectations. Low PE means the stock is priced cheaply relative to what the company actually earns.
Bitcoin has no earnings. But it does have something analogous: the USD value of transactions flowing through its blockchain every day. Bitcoin is fundamentally a payment and settlement network, and the economic activity happening on that network is the closest thing it has to “earnings” — a measure of actual utility rather than speculation.
The NVT Ratio takes that insight and turns it into a metric. It’s one of the oldest onchain valuation models in existence, and despite its simplicity, it has produced remarkably accurate signals at market extremes. Here’s how it works.
What Is the NVT Ratio?
NVT stands for Network Value to Transactions. Willy Woo introduced it in a Forbes article in October 2017, building on an idea he first floated on Twitter in February of that year. The formula is straightforward:
NVT Ratio = Bitcoin Market Cap ÷ Daily On-Chain Transaction Volume (USD)
Market cap is the current price of Bitcoin multiplied by the circulating supply — the same figure used everywhere else in crypto. Daily on-chain transaction volume is the total USD value of all transactions processed on the Bitcoin blockchain in the past 24 hours. This is not trading volume on exchanges — it’s the actual economic activity happening on the Bitcoin network itself: payments, settlements, wallet transfers, and movement of real capital between addresses.
When the ratio is high, Bitcoin’s market cap has grown far above what the network’s actual transaction activity would justify. The market is pricing in a lot of future expectation — speculation running ahead of utility. Historically, this has coincided with periods of overvaluation and elevated crash risk.
When the ratio is low, transaction volume is high relative to market cap — the network is being actively used and the market valuation is grounded in real economic activity rather than speculation. Historically, these periods have represented better value and lower risk.
NVT Signal: The More Practical Version
The standard NVT Ratio has one practical problem: daily transaction volume is extremely noisy. A single large transfer — a whale moving 10,000 BTC between wallets — can spike the daily number and temporarily distort the ratio. Woo’s original version smoothed this with a 14-day moving average, but that still left significant noise.
In February 2018, analyst Dmitry Kalichkin published an improvement called NVT Signal (NVTS), which Woo subsequently refined further. NVT Signal uses a 90-day moving average of daily transaction volume instead of raw daily volume. This produces a much smoother, more reliable reading that better represents the underlying trend in network usage rather than reacting to individual days.
The formula for NVT Signal is:
NVTS = Market Cap ÷ 90-Day Moving Average of Daily On-Chain Transaction Volume
NVT Signal is the version most analysts use in practice today. You can view it free at Woobull’s NVT Signal chart and Bitcoin Magazine Pro’s Advanced NVT Signal chart, which adds standard deviation bands to identify when the reading is statistically extreme.
How to Interpret NVT: What High and Low Mean
Unlike some onchain metrics, NVT doesn’t have universally agreed threshold values — the “right” level has drifted over Bitcoin’s history as the network has matured. What matters most is the relative reading compared to its own historical range, and whether it’s at an extreme.
A high NVT reading — well above the historical norm — indicates the market is paying a large premium over what the network’s actual transaction activity justifies. Think of it as investors being willing to pay a very high PE multiple: they’re buying future potential, not current utility. Every major Bitcoin bubble has seen the NVT Ratio climb to historically elevated levels before the correction. The 2017 peak, the April 2021 peak, and the late 2025 peak all registered NVT readings that were significantly above the long-term average.
A low NVT reading — well below the historical norm — indicates the network is being actively used and the market cap is grounded in real economic activity. This has historically appeared during periods of undervaluation, bear market bottoms, and the early stages of recovery when transaction volume is growing faster than price. The Thermocap Multiple tells a similar story from the miner cost angle — when both NVT and Thermocap Multiple are low simultaneously, the valuation case is reinforced from two different analytical directions.
The Adjusted NVT Signal, available on Bitcoin Magazine Pro, makes this interpretation easier by expressing the reading in terms of standard deviations above or below the 2-year historical norm. A reading at +2 standard deviations is historically extreme and has coincided with overvaluation. A reading at -1 or below is historically undervalued territory.
Historical Examples: Where NVT Called the Turns
The 2017 bubble is the cleanest historical example. As Bitcoin’s price ran from $1,000 in January to nearly $20,000 in December, transaction volume didn’t keep pace — much of the price appreciation was pure speculation rather than network utility growth. The NVT Ratio climbed to historically extreme levels, signaling that market cap had far outrun the economic activity happening on chain. The crash that followed took Bitcoin from $20,000 to $3,200 over the next year.
The recovery in 2019 showed the opposite reading. As Bitcoin bounced from $3,200 toward $14,000 in mid-2019, on-chain transaction volume was growing robustly — real economic activity was expanding alongside price. The NVT Ratio remained relatively contained through that rally, suggesting the move had genuine utility support rather than being pure speculation. The subsequent correction was less severe and shorter than the 2018 bear market.
The 2021 double-peak cycle showed a more nuanced picture. The April 2021 peak at $58,000 registered a high NVT reading, and the subsequent crash to $30,000 followed. The November 2021 peak at $69,000 registered a comparatively lower NVT than the April peak — transaction volume had grown significantly through the year — which some analysts argued signaled a healthier structural foundation. The correction that followed, while still severe (Bitcoin fell to $16,000 in 2022), took considerably longer to unfold than post-2017.
The Lightning Network Problem: NVT’s Most Important Limitation
No honest discussion of NVT is complete without addressing its most significant structural limitation: the Lightning Network.
The Lightning Network is Bitcoin’s layer-2 payment protocol, which processes small, frequent transactions off the main blockchain — settling them periodically rather than recording every individual payment on-chain. It’s become a significant part of Bitcoin’s payment infrastructure, particularly for small, everyday transactions. Woo himself acknowledged this issue when Liquid (Bitcoin’s first sidechain) went live in October 2018, noting that “NVT will need recalibration” as off-chain volume grows.
The problem for NVT is that Lightning Network transactions are invisible to the metric. They don’t appear in on-chain transaction volume because they don’t happen on the main blockchain. As Lightning adoption has grown through 2024 and 2025, an increasing share of Bitcoin’s genuine economic activity is simply not captured by NVT. This causes NVT to read artificially high — market cap appears more elevated relative to “transaction volume” than it actually is, because a growing chunk of real transaction volume is happening off-chain.
The Adjusted NVT Signal partially addresses this by normalizing the reading to its historical average — so the relative comparison is still meaningful even if the absolute number has drifted. But it’s important to understand that raw NVT Ratio readings today are not directly comparable to readings from 2017 or 2019, when Lightning was negligible. The metric’s utility is strongest when used to identify statistically extreme readings relative to recent history, rather than comparing absolute values across different eras.
NVT vs. Thermocap: Two Different Valuation Questions
NVT and Thermocap Multiple are both Bitcoin valuation models, but they’re asking fundamentally different questions and measuring completely different things.
NVT asks: is Bitcoin’s market cap justified by the economic activity happening on its network right now? It’s a usage-based valuation — grounding market cap in how much real value is flowing through the blockchain. It’s most sensitive to changes in on-chain transaction behavior and responds relatively quickly to shifts in network usage.
Thermocap Multiple asks: is Bitcoin’s market cap a rational premium over the cumulative cost of securing the network since 2009? It’s a security-cost-based valuation — grounding market cap in the real-world capital expenditure that has gone into building and maintaining the infrastructure. It moves very slowly and captures long-term cycle extremes rather than shorter-term deviations.
When both metrics point in the same direction — both elevated (potential overvaluation) or both compressed (potential undervaluation) — the signal is reinforced. Right now, with Bitcoin down approximately 47% from its October 2025 peak, both metrics are at more moderate readings than they were near the top, consistent with the broader picture painted by MVRV Z-Score and the other metrics tracked in the Onchain Pulse.
How to Check NVT for Free
Woobull’s NVT Ratio chart is the original, created by Willy Woo himself and freely available with no account required. It shows the smoothed NVT Ratio alongside Bitcoin’s price. Woobull’s NVT Signal chart shows the 90-day MA version — the one most analysts use for actual signals. Bitcoin Magazine Pro’s Advanced NVT Signal adds standard deviation bands that make it easier to identify statistically extreme readings at a glance. All three are free.
Like Thermocap, NVT is a slow-moving, macro-level indicator. Check it monthly or when Bitcoin makes a major move — daily fluctuations in transaction volume create noise that isn’t meaningful for long-term investors. What you’re looking for is sustained elevation above or compression below the historical range, not day-to-day wiggles.
The Bottom Line
NVT Ratio is an elegant idea grounded in a simple truth: a payment network’s value should have some relationship to how much economic activity flows through it. When Bitcoin’s market cap races far ahead of that activity, the premium over utility is expanding — historically a warning sign. When market cap compresses toward the level justified by actual usage, historical value windows open.
Its Lightning Network limitation means it requires more interpretive nuance than it did in 2017. But used in conjunction with the broader suite of onchain metrics — MVRV, Thermocap, SOPR — NVT adds a genuinely distinct signal that no other metric provides: a usage-based valuation check that keeps market sentiment anchored to something real.
