Overview

Realized Cap 10y+ is the total cost basis of UTXOs that have not moved in over 10 years. This includes Satoshi-era coins valued at their original (near-zero) acquisition prices.

Formula

$\text{Realized Cap}_{10y+} = \sum_{\text{age} \geq 3650\text{ days}} \text{amount}_i \times \text{price}(\text{cohort\_date}_i)$

Interpretation

• Near-zero aggregate cost basis since most of these coins were acquired when Bitcoin was worth cents to single-digit dollars.
• Despite holding substantial supply, this cohort contributes minimally to the total Realized Cap.

Use Cases

• Quantify the cost basis of the oldest, likely-lost supply
• Contextualize the Realized Cap contribution of dormant supply
• Track changes if any extremely old coins are spent
