## Core charts

- [The Rainbow Chart](https://btcoak.com/rainbow): Bitcoin's price since genesis in logarithmic space, divided into nine valuation bands.
- [Stock-to-Flow](https://btcoak.com/stock-to-flow): A scarcity-based valuation model. Price as a function of existing supply divided by new annual issuance.
- [Power-Law Corridor](https://btcoak.com/power-law): Bitcoin's price bounded by a narrowing log-log corridor, first described by Giovanni Santostasi.
- [Pi Cycle Top](https://btcoak.com/pi-cycle): Two moving averages whose crossover has historically landed very close to Bitcoin's major cycle peaks.
- [200-Week Moving Average Heatmap](https://btcoak.com/200w-ma): Long-term support line, colored by its four-week rate of change.
- [Fear & Greed Index](https://btcoak.com/fear-greed): A 0–100 composite of volatility, momentum, dominance, social, and survey signals. A read on market sentiment.
- [Puell Multiple](https://btcoak.com/puell-multiple): Daily issuance value divided by its 365-day average. Miner-revenue regime as a cycle lens.
- [Net Unrealized Profit / Loss](https://btcoak.com/nupl): The fraction of all BTC currently held at a paper profit. Zero is the break-even network.
- [Bitcoin ETF Flows](https://btcoak.com/etf-flows): Daily net flow into US spot Bitcoin ETFs since January 2024. Cumulative inflows and AUM alongside.
- [Exchange Reserves & Net-Flow](https://btcoak.com/exchange-flows): Total BTC held on centralised exchanges, paired with the 30-day aggregate net inflow.
- [Coinbase Premium Index](https://btcoak.com/coinbase-premium): Price delta between Coinbase Pro and Binance. Positive spikes tag US-institutional accumulation; sustained negatives have preceded distribution phases.
- [AHR999 Index](https://btcoak.com/ahr999): A dollar-cost-averaging index built from the short-run price and its 200-day geometric mean. Under 0.45 marks the DCA zone; over 1.2, overbought.
- [Reserve Risk](https://btcoak.com/reserve-risk): Price divided by the accumulated HODL bank — long-term-holder conviction relative to price. A log-scale index that typically ranges from 0.0005 to 0.05.
- [RHODL Ratio](https://btcoak.com/rhodl): The ratio of 1-week to 2-year realized-cap bands. A cycle-top lens — peaks when recently-moved coins dominate the realized-cap distribution.
- [STH / LTH SOPR](https://btcoak.com/sopr): Spent-Output Profit Ratio split by holder age. Above 1 means coins are being spent at a profit; below 1 means loss. Short-term and long-term crossings frame cycle regimes.
- [STH / LTH Realized Price](https://btcoak.com/realized-price): Average cost basis of coins by holder age cohort. Spot against short- and long-term realized prices — a classic support and resistance band for cycle bottoms and tops.
- [Golden-Ratio Multiplier](https://btcoak.com/golden-ratio): Philip Swift's 350-day-MA Fibonacci band. Six multipliers (1.6, 3, 5, 8, 13, 21) mark progression from accumulation to late-cycle excess; later peaks have tended to top out in lower bands.
- [Long/Short Ratio](https://btcoak.com/long-short): Ratio of long to short accounts on the top perpetual-futures venue. A contrarian positioning lens — crowded longs precede flushes, crowded shorts precede squeezes.
- [Funding Rate](https://btcoak.com/funding-rate): Volume-weighted perpetual-futures funding rate. Positive means longs pay shorts; negative means shorts pay longs. A real-time read on leverage imbalance.
- [Open Interest](https://btcoak.com/open-interest): Total USD value of outstanding Bitcoin futures contracts across exchanges. Rising OI into price rallies marks leverage build-up; flushes mark deleveraging.
- [Liquidation Heatmap](https://btcoak.com/liquidations): Aggregate long- and short-liquidation clusters over the last year, shown as a price × time density grid. Bright cells are magnet zones price tends to seek.
- [Bitcoin Dominance](https://btcoak.com/dominance): Bitcoin's share of the total crypto market cap, 2013 to today. The cleanest lens for BTC-versus-alt regime.
- [Stablecoin Market Cap](https://btcoak.com/stablecoin-supply): Total USD stablecoin market cap — USDT, USDC, DAI, and the rest. A proxy for dry powder waiting to deploy.
- [Altcoin Season Index](https://btcoak.com/altcoin-season): A 0–100 index. Zero is pure Bitcoin season, one hundred is pure altcoin season — measured directly against the top-50 alts.
- [BTC vs Global M2](https://btcoak.com/btc-vs-m2): Bitcoin price against global (or US) M2 money supply. Two log scales, 180-day rolling correlation, optional basket toggle.
- [Drawdown from All-Time High](https://btcoak.com/drawdown): Percentage below the running all-time high on every historical day. The canonical bear-market shape, annotated with every cycle-trough anchor.
- [MVRV Ratio](https://btcoak.com/mvrv): Market capitalisation divided by realized capitalisation — Bitcoin's price-to-book. Readings below one have marked the deepest capitulation windows.
- [MVRV Z-Score](https://btcoak.com/mvrv-z): The Awe & Wonder standardisation of MVRV. Above +7 marked the classic early blow-off tops; deep bottoms tend to cluster near +0.1 and below.
- [HODL Waves](https://btcoak.com/hodl-waves): Two-bucket long-term-holder dominance stack. Accumulation into cold storage vs distribution to new hands, day by day.
- [Daily Issuance](https://btcoak.com/issuance): New Bitcoin issued per day — a step function halving every four years. USD value and annualised inflation alongside, with the countdown to the next halving.
- [Rolling CAGR](https://btcoak.com/rolling-cagr): Compound annual growth rate over 1, 3, 5, and 10-year rolling windows. The Bitcoin returns-by-period question answered in one chart.
- [Rolling Volatility](https://btcoak.com/volatility): Annualised stddev of daily log returns across 30, 90, and 365-day windows. The long-run maturation story — vol compressing every cycle.
- [Profitable Days](https://btcoak.com/profitable-days): Every historical day coloured sage or rust — would buying that day have been profitable at today’s price? A visual bear-market anatomy of the holding history.
- [Halving-Cycle Overlay](https://btcoak.com/halving-cycles): Four halving cycles normalised to day 0 — how every post-halving price run compares at the same days-since elapsed.
- [Time in Band](https://btcoak.com/time-in-band): Asymmetric time-distribution across the Rainbow valuation bands. Years in the lower bands, weeks in the Euphoric.
- [Monthly Returns Heatmap](https://btcoak.com/monthly-returns): Bitcoin’s monthly return grid — years as rows, months as columns, coloured by sign and magnitude. The evergreen seasonal-performance reference.
- [Hash Rate](https://btcoak.com/hash-rate): Total computing power securing the Bitcoin network, 2009 to today. Grows with price in log space; sharp drawdowns mark miner capitulations.
- [Hash Ribbon](https://btcoak.com/hash-ribbon): Charles Edwards' 30/60-day hash-rate crossover. Capitulation below, recovery above. This page marks every raw recovery upcross.
- [Active Addresses](https://btcoak.com/active-addresses): Daily unique addresses that transacted on the Bitcoin network. Saturates above a million at cycle peaks; bottoms near 500k in deep bears.
- [New Addresses](https://btcoak.com/new-addresses): First-time addresses created per day. A stronger adoption signal than total active — measures on-boarding rather than circulation.
- [Bitcoin Correlations](https://btcoak.com/correlations): 90-day rolling correlation of Bitcoin with gold, small-caps, Nasdaq-100, S&P 500, and long-bonds. Is BTC digital gold, tech stock, or independent?
- [Daily Transaction Count](https://btcoak.com/transactions): Daily confirmed on-chain transactions. Saturates near 300–500k per day under the block-size ceiling; the 30-day average reads network usage through fee-market regimes.
- [Daily Fees](https://btcoak.com/fees): Total USD transaction fees paid to miners each day. Halving-day spikes and ordinals/runes events stand out against four orders of magnitude of history.
- [NVT Ratio & Signal](https://btcoak.com/nvt): Market cap divided by daily on-chain transaction volume. Bitcoin's price-to-utility ratio — Woo's original NVT plus Kalichkin's 90-day smoothed NVT Signal.
