Peer-reviewed foundation: realized value is the credible on-chain cost basis the whole field builds on
ORIGINATED BY Realized Cap: Nic Carter & Antoine Le Calvez (Baltic Honeybadger 2018, inspired by Pierre Rochard). MVRV: David Puell & Murad Mahmudov (Oct 2018).
*Every coin has a memory. The last price at which a bitcoin moved is stamped, immutably, on the chain — a receipt no exchange can lose and no trader can revise. Sum those receipts across all sixteen-odd million coins and you get something no equity market can offer: the aggregate cost basis of an entire asset, computed from first principles. Divide today's market price by that cost basis and you have a single number that asks the only question that matters at a top or a bottom — how far has the crowd drifted from what it actually paid?*
Market value is the number everyone knows: today's price multiplied by the coins in existence. It is a snapshot of collective mood, and mood is volatile. Realized value is the quieter, sturdier cousin. Instead of pricing every coin at today's quote, it prices each unspent output (UTXO) at the BTC/USD price the last time that coin moved on-chain. Aggregate those and you get realized cap — an approximation of what the network as a whole actually paid for its coins. In the authors' own words, the UTXOs are 'aggregated and assigned a price based on the BTCUSD market price at the time when said UTXOs last moved.' It is an on-chain cost basis, reconstructed transaction by transaction.
MVRV is then almost embarrassingly simple: market value divided by realized value. When the ratio is high, the market is pricing coins far above what holders paid — a large unrealized gain sits on the table, and history says holders eventually reach for it. When the ratio is near one, price has fallen back to the network's cost basis: the average coin is roughly break-even, sellers are exhausted, and the downside compresses. The intuition is behavioural, not mystical — it is a market-wide profit-and-loss gauge inferred purely from public data.
The lineage matters. Realized cap was introduced by Nic Carter of Castle Island alongside Antoine Le Calvez of Blockchain.info at Baltic Honeybadger 2018, building on a spent-output valuation idea credited to Pierre Rochard. It solved a real problem: market cap treats a coin lost in 2011 and a coin bought this morning as identical, which badly overstates the capital genuinely committed to the network. Realized cap discounts long-dormant coins toward their ancient, low cost basis, giving a truer picture of invested capital.
In October 2018 David Puell and Murad Mahmudov took realized cap and built the ratio on top of it, then went looking for empirical structure. They found two levels that had, historically, marked extremes: an MVRV around 3.7 clustered near cyclical tops (overvaluation), and an MVRV around 1.0 clustered near cyclical bottoms (undervaluation). Those numbers are the reason this module exists — not because they are laws of nature, but because they were the first credible, reproducible, on-chain valuation bands anyone had published. Nearly every cycle-timing metric that followed is a descendant of this work.
Read it as a foundation, not an oracle. Realized value is the genuinely rigorous contribution here: a defensible, transparent way to compute an asset's cost basis from the ledger itself. MVRV is the honest first application of that idea. The thresholds are where the intellectual honesty gets tested — and, as we'll see, where even the original authors told you to be careful.
THE MATHS
Realized Value (RV) = Σ over all UTXOs of ( coin_amount × price_when_last_moved ) Market Value (MV) = current_price × circulating_supply MVRV = MV / RV [≈ 1.0 historically marks bottoms; ≈ 3.7 marked tops]

Where this indicator lies to you.
The headline weakness is the 3.7 upper bound, and the sharpest critics of it were Puell and Mahmudov themselves. In the original 2018 piece they wrote that 'as market cap decreases in volatility, we believe that the upper threshold of MVRV might not prove as reliable — as market cap overextends less and less above realized cap as time progresses.' In plain terms: as Bitcoin matures and its volatility compresses, price simply doesn't blow as far above cost basis as it once did. A threshold fitted to the wild 2013 and 2017 tops is not guaranteed to be touched in a calmer future top — which is exactly the out-of-sample decay the authors flagged. Treat 3.7 as a historical artefact, not a trigger.
The deeper problem is small-sample overfitting. Bitcoin has produced only a handful of complete cycles, so any threshold 'calibrated' on tops and bottoms is fitted to a pitifully small number of events. Two or three data points can always be connected with a tidy line drawn in hindsight; that line tells you almost nothing about the next event. The metric's transparency is a virtue, but it does not rescue the thresholds from the fact that they describe the past far better than they predict the future. The lower band near 1.0 is more defensible — it rests on a real economic floor (aggregate break-even and seller exhaustion) rather than on a fitted extreme — but even it is not a promise.
Finally, realized value has structural blind spots. Lost coins are still counted at their last-moved price, quietly distorting the cost basis. Internal transfers, exchange restructures, and self-sends can re-stamp coins at prices that don't reflect genuine buying, injecting noise. And the ratio is a coincident-to-lagging read of aggregate psychology, not a leading signal — it tells you the crowd is stretched, never precisely when the rubber band snaps. Use MVRV to gauge where in the cycle sentiment sits; never use a single threshold crossing as a standalone buy or sell instruction.
