Updates

Spent Output Age Bands added

Added Spent Output Age Bands (SOAB), showing the age structure of spent outputs as stacked share bands, with BTC price for market context. SOAB reads spent-side activity by output count, making it the count-weighted companion to Spent Volume Age Bands (SVAB).

Band isolation keeps a selected age band in its true stacked position instead of collapsing it to the bottom, so you can inspect one cohort without losing its place in the full distribution.

New paired and comparison metrics

Added a new group of Bitcoin charts that place related series in the same view: holder cost basis, supply-side balance, miner economics, and capital structure.

New charts:

• Bitcoin STH Realized Price vs LTH Realized Price
• Bitcoin Realized Cap vs Market Cap
• Bitcoin Supply in Profit and Loss (BTC)
• Bitcoin Transaction Fees vs Miner Revenue
• Bitcoin Thermo Cap vs Market Cap

Also includes minor fixes around paired chart rendering, legend behavior, and chart interaction.

Early price history, axis sync, and mobile fixes

Updated the methodology for Bitcoin’s earliest price history. Early BTC markets were thin and fragmented, so small differences there shift long-horizon valuation readings.

This affects charts anchored to historical BTC price or market-value calculations: BTC Price, Market Cap, Realized Price, STH Realized Price, LTH Realized Price, MVRV, MVRV Z-Score, NUPL, and Supply in Profit / Loss.

Added axis sync on Realized Price, STH Realized Price, and LTH Realized Price. The left and right axes now share a scale, so price overlays line up directly without manually rescaling either side.

Fixes log-scale panning on mobile and makes touch panning smoother. Includes minor bug fixes.

Supply in Profit / Loss

Added Supply in Profit / Loss, a composite Bitcoin metric showing the share of circulating supply currently valued above or below its realized cost basis. BTC price is included for market context.

This update also includes bug fixes and interface refinements across the chart workspace.

CoreCharts Version 2

CoreCharts Version 2 introduces a redesigned chart interface with more space for data, cleaner metric reading, and faster interaction across the platform.

Current metric values are now shown directly on the chart, visible at a glance without leaving the visual context. Charts with bands and layered areas have been reworked for more stable rendering and cleaner hover behavior.

Mobile chart interaction has been fully rebuilt. Inspect mode, touch gestures, zoom, and chart navigation are now consistent across screen sizes, with scrolling and inspection separated more cleanly.

Performance has been improved across heavier charts and older devices. Several reported issues have also been fixed in this release. If you notice something that does not work as expected, contact us at bugs@corecharts.com.
