Mark the same coins two ways
Suppose a fictional ledger has two unspent outputs holding all five coins. One holds two coins created on a day when the reference price was USD 100 per coin. The other holds three coins created on a day marked at USD 200 per coin. The current reference price is USD 300 per coin.
| Marking rule | Calculation | Value (USD) |
|---|---|---|
| Mark each output at its creation-day price | 800 | |
| Mark all five coins at today's price | 1,500 |
A wallet move can change the ratio
Keep spot at USD 300 and suppose the owner spends the older two-coin output to a fresh address in their own wallet, with no fee in this example. The old output drops out of the snapshot. Its replacement enters at today's price, changing its realized contribution from USD 200 to USD 600. Realized cap rises to USD 1,200 and MVRV falls to 1.25. Ownership, supply and spot price are identical across the two snapshots.
What makes two readings comparable?
- Unit of observation. Coin Metrics dates a UTXO by its creation day. On an account-based chain it uses the more recent of account creation and the last day the account sent a ledger change to date the balance. Glassnode's entity-adjusted Bitcoin variant instead uses address clustering to estimate common control and filter movements it classifies as internal. Cluster errors can leave self-transfers in the calculation or filter out actual transfers between entities. Coin Metrics, Realized Market Cap · Glassnode, Entity-Adjusted MVRV.
- Supply and USD marks. The per-coin identity above needs matching supply. Coin Metrics' free-float variant deliberately changes the numerator to free-float market cap while keeping the realized-cap denominator. A close also depends on the chosen price series and cutoff. When a USD series uses non-USD trades, it needs an explicit conversion rate for the quote asset. Coin Metrics, Free Float MVRV · Coin Metrics, Reference Rate Metrics.
- Snapshot and data vintage. A chain reorganisation can replace the block used for a recent snapshot and change which outputs were unspent at the cutoff. In an entity-adjusted series, newer address evidence can also revise historical estimates. A historical study that uses revisions available only after its decision time can introduce look-ahead bias.
