Revived Age by Vintage Year (USD)
Stacked USD valuation by year-of-birth cohort - amplifies the impact of each vintage class on total network valuation through bull markets.
What is it?
Revived Age by Vintage Year (USD) is the valued counterpart of #317 BTC. For each vintage class, we multiply this cohort's BTC supply by daily spot BTC price. This gives the instant USD valuation of each generation. The difference with #317: a cohort's BTC quantity may be stable, but its USD valuation grows dramatically in a bull market (price effect). The total stacked-area equals total Bitcoin Market Cap.
How to read
Stacked-area absolute in USD with log scale. Read from bottom (2009 cohort) to top (current cohort). In a bull market, all bands widen simultaneously (global price effect), but old cohorts (2009-2013) with a stable BTC supply may inflate in USD faster than recent cohorts (low cost basis leverage effect).
Key zones
The 2009 cohort valued at a bull price may represent tens of billions USD, a significant fraction of total Market Cap. The 2017-2021 cohorts typically dominate total valuation in advanced bull markets (acquisitions at mid-prices, large supply). Recent cohorts (year-of-birth ≥ current_year - 2) have moderate USD weight (little supply accumulated yet).
What to observe
The USD-vs-BTC evolution of each cohort is revealing: if the 2009 cohort sees its USD share explode without BTC supply change, it is a pure price-rise effect. If a recent cohort loses USD during a bear market while its BTC supply remains stable, it is the price-decline effect. Cross-reference with #319 Revived Year Cost Value to compare current USD valuation vs the cumulative cost basis of each vintage.
Historical context
Historical bull markets saw explosions of total USD valuation, dominated by old cohorts (2010-2017) which weigh disproportionately in USD despite sometimes modest BTC supply. Bear markets bring USD stratification back toward BTC stratification (price effect neutralised). Post-ETF 2024 introduces new dynamics: recent cohorts gain USD weight faster than in the past (accelerated institutional absorption).
Expert notes
The stacked total sum strictly equals Bitcoin Market Cap. This property enables verification: if the sum diverges from separately calculated Market Cap, there is a data bug. For premium analysis, compare the USD-cohort / BTC-cohort ratio for each vintage: it is the 'unrealized profit factor' per generation. A 2009 cohort with ratio > 1000x indicates a massive OG unrealized profit.
Common mistakes to avoid
Common mistake: concluding that a 'USD-rich' old cohort is necessarily profitable for its holders. If this cohort's coins are durably dormant (e.g., Patoshi), the USD valuation remains theoretical: no realization possible. Always distinguish potential valuation (#318) from actually realized PnL (#322 cumulative net).
